1B). Isoflavones containing a genistein core were found in a slightly higher proportion than those containing a daidzein core, 52.4% and 42.4%, respectively. Only 5.2% of isoflavones contained a glycitein core. In general, these relative contents were different than those of other studies (Genovese and Lajolo, 2002, Murphy et al., 1997 and Setchell et al., 1997), which reported higher proportions of isoflavones containing genistein (mean of 61%) and glycitein cores (mean of 9%) and lower proportion of daidzein core isoflavones (mean of 30%). Daidzein and genistein have been shown to have a weak oestrogenic activity and are able to bind with a low affinity to oestrogen receptors

(Fehily, 2003). In relation to antioxidant activity, it Panobinostat has been reported that genistein is more effective than daidzein, since the former contains two hydroxyl groups while BMN 673 in vitro the latter contains only one. Moreover, glycitein shows a reduced antioxidant activity due to the blocking of hydroxyl through methylation (Rüfer and Kulling, 2006). Soyasaponins contents in the analysed infant formula samples

are given in Table 4. The total soyasaponins contents ranged between 17.9 and 113.5 mg/100 g, with a mean content of 55.0 mg/100 g (Table 4). The large variation of total soyasaponins contents observed in our samples is probably a reflection of the soy protein composition used in the formula’s manufacture and agrees with data from Murphy et al. (2008), which reported a wide range of 71.8–320.7 mg/100 g. Murphy et al. (2008) reported that the total soyasaponins mean content of six soy-based

infant formula samples acquired in three different locations in the US was 199.4 mg/100 g, 3.6 times higher than those found in our samples. It should be noted that these authors analysed soyasaponins B-V, B-αg, B-βg and B-βa in addition to B-I and B-II, which were evaluated in the present study, but have not analysed soyasapogenol B, which was found in three of the samples analysed in the present study. Even if we only consider soyasaponins B-I and B-II, the samples analysed by Murphy et al. (2008) showed contents 3.6 times higher (159.9 mg/100 g) than those observed in the present study. The total soyasaponins contents observed in the present study were similar to that tuclazepam reported by Fang et al. (2004) (117.7 mg/100 g), who analysed a soy protein isolate sample. For such comparison, we took into consideration that our infant formulas samples contained a mean of 15.6% of soy protein. The major soyasaponin present in the infant formulas samples was soyasaponin B-I, which corresponded to a mean of 65.5% of total soyasaponins content, with the exception of Nan Soy, in which soyasapogenol B was the most abundant (55.4%) soyasaponin. Soyasaponins B-II and B-III accounted together for 21.7% of soyasaponins content.

A similar reduction occurred in 1998, when the agency reduced lev

A similar reduction occurred in 1998, when the agency reduced levels from 100 (proposed in 1979) to 80 μg L−1 (Pontius, 1993 and Zhao et al., 2004). Some European countries have stricter laws for THMs. Germany and Switzerland have set the maximum contaminant level at 10 and 25 μg L−1 of total THMs in drinking water (Golfinopoulos & Nikolaou, 2005). THMs are considered BGB324 carcinogenic. Studies suggest

that consumption of drinking water contaminated with high concentration of these compounds increases risks of bladder, kidney, stomach and pancreatic cancers in humans and animals. Therefore, exposure to such compounds should be minimised (Tokmak, Caper, Dilek, & Yetis, 2004). Different analytical methods based on gas chromatography have been reported for determining THMs in drinking water. Most of them consist of a previous separation step

to concentrate analytes, such as liquid–liquid extraction (LLE) (EPA method 551.1, 1995), purge and trap (P&T-GC) (Nikolaou, Lekkas, Golfinopoulos, GDC-0199 research buy & Kostopoulou, 2002), solid-phase extraction (SPE) (Gioia et al., 2004) and headspace solid-phase microextraction (HS-SPME) (Cardinali, Ashley, Morrow, Moll, & Blount, 2004). The current trend in analytical chemistry is to take on “green chemistry” ideology and in this sense, “solvent minimised” or “solvent-free” sample preparation methods have been developed, such as microextraction techniques (Pavón, Martín, Pinto, & Cordero, 2008). The SPME technique, developed by Belardi and Pawliszyn (1989), is free of organic solvent, is simple, sensitive during (Li, Zhong, Xu, & Sun, 2006) and widely applied in the determination of organic pollutants in food samples (Cavaliere, Macchione, Sindona, & Tagarelli, 2008). The principle behind SPME is the distribution of analytes between the sample matrix and a polymeric coating on a fused silica fibre, as well as their subsequent desorption in the injection port of a chromatograph (San Juan, Carrillo, & Tena, 2007). According to the maximum contaminant level for THMs in drinking water established by several agencies, it is expected

that THMs exist in trace levels in soft drinks, thus an extraction/preconcentration technique is required. However, few approaches have been reported for extraction of THMs from several types of soft drink (Abdel Rahman, 1982, Campillo et al., 2004 and Wallace, 1997). The main goal of this study was to explore the potential of the SPME technique for quantification of THMs in several kinds of soft drink matrices commercially available in the city of Florianópolis (capital of the state of Santa Catarina, Brazil). To reach this goal, the optimisation of the parameters affecting the THM extraction using the SPME fibre was performed by univariate method. The variables were temperature and extraction time, agitation speed, addition of NaCl and headspace volume.

The comprehensive 1H-NMR and 13C-NMR spectral data of compounds 1

The comprehensive 1H-NMR and 13C-NMR spectral data of compounds 1–21 are worth determining for the structures of the less polar ginsenosides as some of their 1H-NMR and 13C-NMR spectroscopic

data are not available. Other data are either scattered throughout published papers, or dated, therefore it is hard to compare the structures of the isolated compounds. PF-01367338 mw In the study, the results were assigned using one-dimensional and two-dimensional NMR spectroscopic methods and were also confirmed by comparison with previously published data. Some signals, such as those for the methyl groups of C-26–C-30 and the saturated methylenes, which have not been reported previously, were unambiguously determined using two-dimensional NMR spectra including 1H-1H COSY, HSQC and HMBC spectra. The 13C-NMR spectral data suggested the

following information for the structural elucidation of the ginsenosides isomers. First, the chemical BGB324 shifts of the characteristic peaks between the 20(S) and 20(R) ginsenosides provided information for the identification of the stereoisomers. In particular, changes in the chemical shifts between the S- and R- forms at C-17, C-21 and C-22 in the 13C-NMR spectra were approximately Δδ (δS – δR) +4.1 ± 0.1, +4.3 ± 0.1, and −7.4 ± 0.1 ppm, respectively ( Table 2 and Table 4). Next, the presence of the signal (δC 88.8 ± 0.1 ppm) of the hydroxyl carbon at C-3, which did not overlap with other hydroxyl groups in the backbone and the sugar moieties, easily indicated whether it was a PPD- (1–8, 17, and 20) or PPT-type (9–16 and 18). In addition, the signals at δC 170.6 ± 0.1 showed the existence

of the acetyl groups (5, 6, 15, and 16) ( Table 2 and Table 4). It was assumed that they were produced from the malonyl moiety by decarboxylation during the manufacturing process and were located at C-6 in the glucose group (5, 6, 15, and 16) [23]. Finally, the chemical shifts of the down-field signals indicated the type of backbones. The values for a double bond at Δ24(25) in 3,12,20-trihydroxydammar-24-ene and 3,6,12,20-tetrahydroxydammar-24-ene (1–6, 9–12, 15, and 16) were δC 126.1 ± 0.2 (C-24) and 130.1 ± 0.1 (C-25), respectively ( Table 2 and Table 4). However, they were shifted to δC 124.2 ± 1.0 and 131.2 ± 0.0 as a result Liothyronine Sodium of the dehydration at Δ20(21) (17) or Δ20(22) (18 and 20) ( Table 6). The differences between the chemical shifts of δC 155.5 and 108.1, and of δC 140.1 ± 0.1 and 123.4 ± 0.2 ppm indicated the discrimination of 3,12-dihydroxydammar-20, 24-diene (17) and 3,12-dihydroxydammar-20(22),24-diene (18 and 20). These results were in perfect agreement with previously published values [21], [24] and [25]. Compound 21, an oleanane-type triterpene, might be produced by the selective hydrolysis of sugar residues at C-3 in ginsenoside Ro [26] ( Table 6). All the contributing authors declare no conflicts of interest.

Thus, it is possible that many of the forest ecosystems currently

Thus, it is possible that many of the forest ecosystems currently showing strong N retention were at one stage N-saturated. These results further suggest that N leaching is not a particularly effective means by which to reduce ecosystem N status. N once retained in these systems does not leach back out again, and Pexidartinib mw N leaching in N-saturated systems appears

to be more a function of inputs than of ecosystem pool sizes. This is in contrast to the potential for N leaching in non-N-saturated systems, where the potential for N leaching with increased inputs is very much related to current N status; specifically, on how close they are to N saturation at the time (Gunderson et al., 1998). By far the least known and most seldom measured process of N export is denitrification. In theory, N export by microbial denitrification should be minimal except under anaerobic conditions in the presence of organic matter (Paul and Clark, 1989). So-called chemodenitrification – the chemical reactions by which nitrite is converted to gaseous forms – can also occur under aerobic conditions such as after the first stage of nitrification. Denitrification can be a substantial learn more loss under anaerobic conditions and following fertilization, but it is considered to be generally

a minor component of N export in well-drained forest ecosystems (Barton et al., 1999, Groffman and Tiedje, 1989, Neilson Tau-protein kinase et al., 1994 and Vermes and Myrold, 1992). Exceptions may occur, however, especially following disturbance when nitrate concentrations are high (Vermes and Myrold, 1992). Case studies of quantitative change in soil or ecosystem content estimated using budget approaches that the authors are aware of are listed in Table 2. We included only studies that were not fertilized with N, had no N-fixing vegetation, and only cases where soils were resampled over time. We excluded chronosequence studies because of the uncertainties with initial soil N contents. The studies were broken into three categories: (1) those where total ecosystem N (vegetation, forest floor, and soil) N changes were reported;

(2) those where only soil and/or forest floor N changes were reported; and (3) “sandbox studies” where N increments in artificially constructed lysimeters or backfilled plots were reported. Some of these studies have been previously reviewed by Binkley et al. (2000). Nitrogen changes in ecosystems occur as net changes in the soil, litter and biomass components. Each of these have differing levels of reliability with litter and then biomass changes being the most reliable. In our analyses we have identified these components and have looked at the changes in pools sizes from repeated samplings. No attempt has been made to reconcile analyses of process studies (e.g. N fixation estimates) with pool changes. Johnson et al.

While no detailed records detailing the larval development of Car

While no detailed records detailing the larval development of Carabus species in China are currently available, some Carabus spp. in Europe are known to live for several years and reproduce more than once, and an individual’s development can take more than one season in poor environmental conditions

or when food availability is low ( Lövei and Sunderland, 1996). Such characteristics could partly explain the observed inter-annual variations. Overall, this study provides important insights into the different carabid communities found in plantations and secondary forests in northern China. Despite the history of widespread deforestation in the 1960s, forest specialist species preferring closed forest canopies appear to have persisted, presumably in remote, small pristine

forest islands in the mountainous landscapes, from where they successfully re-colonised the Cilengitide manufacturer newly-establishing secondary forests and forest plantations. Different forest types furthermore clearly support distinct assemblages, with north-exposed birch and larch forests harbouring highly abundant, species-poor and homogeneous ground beetle communities, while secondary mixed forests contain the highest α-diversity in ground beetles, hence contributing significantly to γ-diversity. At the same time, mixed forest beetle assemblages are distinctly different to both, pine and oak forests. The high degree of spatial aggregation exhibited by many carabid species and their low overall abundances support our assumptions that they are chiefly limited to small, distinct habitat AT13387 mw patches. The most appropriate restoration strategy for carabid beetle diversity and the potential associated control of invertebrate pest species across this forest landscape therefore needs to involve the maintenance of both within-stand and between-stand heterogeneity, with particular emphasis on variations of canopy closure. Future forest plantations should be developed with a strong focus on locally native species to further support the colonisation of remnant populations of forest

specialists into China’s new forests. This study was cAMP facilitated by the support and generous funding of the Chinese Academy of Sciences Fellowship for International Scientists (Fellowship Number 2011T2S18), the “111 Program” from the Bureau of China Foreign Expert – Ministry of Education (contract no. 2008-B08044) and the National Science Foundation of China (no. 31270478). Eleanor Warren-Thomas was also supported by a NERC Masters Studentship. We are very grateful to Professor Liang Hongbin and Liu Ye from the Institute of Zoology, Chinese Academy of Sciences, who assisted in identification of a number of difficult species. Duan Meichun provided valuable assistance with specimen preparation. Professor Yu Xiao-Dong kindly provided reprints of his papers that were not available in the UK.

We emphasize, however, that HIV-infected individuals with depress

We emphasize, however, that HIV-infected individuals with depression have varied experiences, and Tenofovir concentration the case examples provided herein are not representative of this population as a whole. When working with this population, it is important that the therapist is aware of co-occurring mental health, medical, and psychosocial problems experienced by their patients. Therapists can optimize treatment response in CBT-AD by either helping to address these varied conditions or facilitating treatment

referrals to other health professionals. Similarly, it is important that the therapist consider the role of patients’ sociodemographic characteristics, such as race and gender, when developing the treatment Selleck CDK inhibitor plan. We acknowledge that our role-play demonstrations are limited to certain patient presentations and reflect those with which the contributing therapists had the most experience. CBT-AD

was developed and tested to treat medication adherence in the context of depression, and this protocol has been found to be efficacious in enhancing adherence and reducing depression in patients with diabetes (Gonzalez et al., 2010 and Safren et al., in press), injection drug-users with HIV infection (Safren et al., 2012), racially diverse HIV-infected adults in an urban setting (Safren et al., 2009), and HIV-infected Mexican Americans (Simoni et al., 2013). However, we also note that the majority of the patients in each of these prior trials of the protocol had additional psychiatric comorbidities, including (but not limited to) anxiety, PTSD, and substance use. When working with patients with multiple comorbidities, practitioners may want to depart Aprepitant somewhat from the CBT-AD protocol in order to treat

these comorbidities with other empirically supported treatments. However, therapists should only depart from the CBT-AD protocol when it becomes clear that a patient’s comorbid conditions are either more severe than their depression and nonadherence, or when the comorbid condition interferes with treatment such that it compromises the ability to complete the protocol or threatens therapeutic alliance. Furthermore, as noted above, this intervention does not specifically address HIV transmission risk behavior. Research among men who have sex with men, the largest group at risk for HIV infection in the U.S., has shown that transmission risk behavior co-occurs with various psychiatric and psychosocial conditions, such as depression, childhood sexual abuse, domestic violence, and substance use (Safren et al., 2011 and Stall et al., 2003).

At the 2013 ICAR, Erik De Clercq recalled how this work led, ultimately, to tenofovir, which was to become a major success for treating HIV-infected patients. From its first introduction in 2001, its market share

has increased to well over 40%. In 2002, having a single-pill regimen was agreed as a way forward to simplify, and thereby enhance, HIV therapy. This led to Atripla being approved in 2006, Complera in 2011 and Stribild in 2012. Tenofovir, in its various prodrug forms, is now available in over 130 countries and is distributed widely to the known HIV-infected population. In line with this research, Piet synthesized phosphonate nucleosides, with a threose sugar moiety, which showed anti-HIV activity in the same range as 9-(2-phosphonylmethoxyethyl) adenine (PMEA). Piet’s work had taken a different pathway. It is possible to link several nucleotides Quizartinib manufacturer together to form aptamers. For example (Fig. 5), the above antiviral nucleosides, which have

a 6-membered ring in place of the natural furanose, could be incorporated into hexitol nucleic click here acid (HNA) aptamers. X-ray studies revealed the structures of HNA–RNA duplexes and HNA–HNA duplexes, the latter having a similar overall form to that of an RNA–RNA duplex with the same base sequence. HNA-containing aptamers were shown to be potent and specific inhibitors of trans-activating region (TAR)-mediated transcription. Normally, an HIV encoded protein, trans-activator of transcription (TAT), binds to cellular factors and to the viral TAR RNA regulatory element, resulting in a vastly increased rate of transcription of all HIV genes. HNA-containing aptamers prevents this interaction and so inhibit HIV replication.

It took four Org 27569 years to engineer a polymerase that would utilise HNAs to assemble a strand complementary to a DNA template. In line with this research, hexitol-modified siRNA has shown good activity in an in vivo anti-HBV model. This success stimulated the concept that it may be possible to generate new forms of biologically active DNA. In order to pursue this idea, a culture system with twin growth chambers was devised. Alternative nutrient media could be fed into the chambers and the culture from one chamber could be used to seed the second chamber, the former culture being removed. In this example, the aim was to replace thymine with 5-chlorouracil (Fig. 6) using Escherichia coli. Initially, the nutrient contained 10% 5-chlorouracil and 90% thymine. With each cycle, seeding one chamber from the previous one, the proportion of 5-chlorouracil was increased. After 180 days, in which there had been about 4000 generations of E. coli, thymine had been replaced totally by 5-chlorouracil. An interesting outcome was that the alternative base led to a change not only in the genotype but also in the phenotype; the “new” E. coli cells were much longer than the original.

, 2012, Gane et al., 2013 and Matthews and Lancaster, 2012) have been developed and show increased viral clearance rates. However, genotype-dependent differences in drug sensitivity and viral resistance highlight the need for additional drugs for future www.selleckchem.com/products/PF-2341066.html combination therapy. The HCV encoded viroporin p7 is an attractive target for therapeutic intervention since it is essential for viral assembly and egress (Tedbury et al., 2011 and Wozniak et al., 2010). However, clinical trials of p7 inhibitors, including the adamantane-derivatives amantadine and rimantadine,

have showed limited efficacy at concentrations that can be achieved in man, consistent with in vitro observations ( Fong et al., 1999, Griffin et al., 2008, Jubin et al., 2000, Steinmann et al., 2007a and Steinmann et al., 2007b). A recent study by OuYang et al., elucidated an NMR structure of HCV p7 strain EUH1480 (GT5A) and predicted the amantadine binding domain. Both amantadine and rimantadine

are suggested to hinder the p7 channel from opening by restricting movement of helical segments in the p7 hexamer. The authors report variations in the adamantane-binding pocket which may explain the broad range of responses to inhibitors reported for diverse HCV genotypes ( OuYang et al., 2013). The majority of in vitro studies on p7 inhibitors have characterised the effect of compounds on virus assembly and the infectivity of secreted Y-27632 2HCl particles. this website However, these studies did not address the ability of HCV to transmit via cell-to-cell contacts, a dominant route of

viral transmission for several HCV genotypes ( Brimacombe et al., 2011, Catanese et al., 2013, Meredith et al., 2013 and Timpe et al., 2008). We therefore assessed the efficacy of several known p7 inhibitors to prevent HCV cell-to-cell transmission, including the amantadine-derivative Rimantadine, the long alkyl-chain iminosugar NN-DNJ ( StGelais et al., 2007 and Wozniak et al., 2010) and the small molecule inhibitor BIT225 ( Luscombe et al., 2010). We previously reported that diverse strains of HCV can transmit effectively via the cell-to-cell route, with J6/JFH (GT2A/2A) showing a distinct preference for cell-to-cell infection, while SA13/JFH (GT5A/2A) transmitted with equal efficiency by either route ( Brimacombe et al., 2011 and Meredith et al., 2013). Furthermore, HCV SA13/JFH is the only published infectious GT5 strain and has a closely related sequence to EUH1480, the subject of the recent p7 NMR study ( OuYang et al., 2013). To determine the sensitivity of HCV J6/JFH and SA13/JFH to p7 inhibitors BIT225, NN-DNJ and rimantadine, infected Huh-7.5 cells were treated overnight with increasing concentrations of compound. The drug was removed by repeated washing, conditioned media was collected over a 2 h period and infectivity measured.

Soils of the Loudonville Series are assigned a K-factor value of

Soils of the Loudonville Series are assigned a K-factor value of 0.32 (Ohio Department of Natural Resources). The pond

is assigned a value of zero as this is the sedimentary basin. The watershed, with exception of a small parking lot in its SW-corner and a fringing housing development in the NW (Fig. 1), which combined make up only ∼15% of the surface area, is characterized as ‘developed open space’ (i.e. the lowest-density urban Selleckchem Talazoparib land-cover type) according to USGS land-cover datasets. This land-cover type infers that impervious surfaces account for less than 15% of the area. This cover is referred to as ‘urban forest’ in this study given a relatively high tree density (Fig. 1 and Fig. 5). The aforementioned exceptions to this forested coverage are presented by a ‘low-intensity development’ cover is comprised of 20–50%

impervious surfaces; a housing development to the NW and a parking lot to the SW of the pond are identified as constituting this land-cover type. Given the absence of steep slopes at both locations, their C-factors should do little to influence overall sediment yield and a uniform C-factor is explored based on the urban forest, which makes up ∼85% of the Selleckchem AT13387 entire watershed cover. Fig. 5 depicts Lily Pond and its watershed for select timesteps from 1938 to 2004 with little change in the distribution and nature of land-cover types. Variance in tree cover and distribution can be assumed negligible over the timeframe of interest as aerial images show no change in tree spacing and canopy density ( Fig. 5). Whereas soil characteristics (i.e. the K-factor), topography (LS-factor), and, in this case, supporting practice (P-factor) generally remain constant through time and are more closely constrained from empirical measurements, the C-factor is nonetheless highly time-variable as seasonal changes Flavopiridol (Alvocidib) to the deciduous forest may have a large imprint on sediment yields. A time-averaged correlation between sediment yield and an appropriate C-factor for the USLE model should present a suitable long-term C-factor for this forested land-cover type given this uniform spatial distribution and

internal homogeneity. Literature sources provide a range from 0.001 to 0.42 for forest cover ( Table 1). Most studies provide little information regarding forest structure that would help estimate a C-factor suitable for the study area; no local study has resolved a C-factor for the forested land cover. The USLE model is therefore run using the lowest and highest C-values in the range provided by the literature (0.001 and 0.42, respectively; Table 1). An assessment of the sediment sequestered within Lily Pond should provide the information necessary to more accurately define the role of vegetation on sediment yield, from which an appropriate C-factor can be derived. All organics in the pond are assumed to represent intrabasinal deposits (i.e. algae, organic detritus, etc.

Mitochondria and

Mitochondria and Torin 1 concentration cytosolic protein extracts were prepared using a Mitochondria Isolation Kit (Pierce) according to the manufacturer’s instructions. Isolated mitochondria were solubilized in

a lysis buffer containing 20mM Tris–HCl (pH 7.5), 1% NP-40, 150mM NaCl, 0.5% deoxycholate, 0.1% sodium dodecyl sulfate (SDS), 2mM MgCl2, 1mM ethylene glycol tetraacetic acid (EGTA), 50mM β-glycerol phosphate, 25mM NaF, 1mM DTT, 1mM Na3VO4 with 2 mg/mL leupeptin, 2 mg/mL pepstatin A, 2 mg/mL antipain, and 1mM phenylmethylsulfonyl fluoride (PMSF). The mitochondrial proteins were then subjected to immunoblotting analysis using antibodies against Bax and Bak. The cytosolic proteins were subjected to immunoblotting analysis using antibody against cytochrome Selleck MAPK Inhibitor Library c. The treated cells were washed with

ice-cold PBS and solubilized in a lysis buffer containing 20mM Tris with a pH of 7.5, 2mM MgCl2, 1mM DTT, 0.5% Triton X-100, 1mM EGTA, 25mM NaF, 1mM Na3VO4, 50mM ®-glycerol phosphate, 2 mg/mL leupeptin, 2 mg/mL pepstatin A, 2 mg/mL antipain, and 1mM PMSF. After incubating on ice for 1 h, the insoluble materials were removed by centrifugation at 14,000 × g for 15 min. 50 μg of protein from each sample was analyzed by SDS-polyacrylamide gel electrophoresis (PAGE), followed by electrotransfer onto a PVDF membrane (Millipore). The membrane was blocked with 5% nonfat milk in PBS with 0.1% Tween 20 and probed with the antibodies. The blots were washed and incubated with a horseradish peroxidase-coupled antimouse immunoglobulin G (IgG) or an antirabbit IgG antibody (Pierce) followed by detection with an electrogenerated chemiluminescence (ECL) revelation system (Bio-Rad). All values are performed in triplicate and expressed as mean ± standard deviation with Microsoft Office 2013 and imaged with Sigmaplot 10 (Systat Software Inc, San Jose, CA, USA). A Student t test was used for quantitative analysis, and the significant Sitaxentan difference is shown as * p < 0.05, **p < 0.01, and ***p < 0.001. To determine the types of ginsenoside in SG, we analyzed MeOH extract of SG by an analytical high-performance

liquid chromatography. As shown in Fig. 1, the amount of four main ginsenosides in the total ginsenosides were 20(S)-Rg3 (11.33%), 20(R)-Rg3 (6.88%), Rk1 (16.72%), and Rg5 (11.97%). As shown in Fig. 1, the amount of ginsenoside Rg3, Rg5, and RK1 reached 50% of total ginsenosides in SG. A number of studies showed that (20S) ginsenoside Rg3, Rg5, and RK1 inhibit cell viability in various human cancer cells. We then examined whether SG features cytotoxic activity in human cancer cells in human cervical adenocarcinoma HeLa cells, human colon cancer SW111C cells, and SW480 cells through an MTT assay. Fig. 2 illustrates that SG exhibited a moderate cytotoxicity against the HeLa, SW111C, and SW480 cells with IC50 values of 94 μg/mL, 78 μg/mL, and 224 μg/mL, respectively.
