Xuesaitong injection (XST), which mainly consists of Panax notoginseng saponins, has been widely used for treating cardio-cerebral vascular diseases. However, the underlying mechanisms of XST associated with its cardioprotective effects are still unclear. To identify the potential target proteins of XST, two-dimensional gel electrophoresis (2-DE)-based proteomics was utilized to analyze the protein profile of myocardium in rats with myocardial ischemia/reperfusion (I/R) injury. The differentially expressed proteins were identified by matrix assisted laser desorption/ionization time-of-flight mass spectrometry...

Ginsenoside Rg1 is a major active constituent of Panax ginseng and possesses anti-inflammatory effects. It has been reported to have therapeutic effects on various diseases. In the present study, we investigated the role of ginsenoside Rg1 in dextran sodium sulfate (DSS)-induced mouse colitis. Our results showed that ginsenoside Rg1 markedly reduces proinflammatory cytokines release upon DSS stimulation of mouse dendritic cells, that ginsenoside Rg1 suppresses IL-1β (Interleukin 1 beta) and TNF-α (Tumor necrosis factor alpha) release via up-regulation of NLRP12 (NACHT, LRR and PYD domains-containing protein 12) expression, and that ginsenoside Rg1 significantly decreases the inflammatory response to DSS-induced mouse colitis, as evidenced by increased body weight, reduced colonic damage scores and disease activity index (DAI), and lowered proinflammatory cytokines levels...

With the advancement of systems biology research, we have already seen great progress in pharmacology studies, especially in network pharmacology. Network pharmacology has been proven to be effective for establishing the "compounds-proteins/genes-diseases" network, and revealing the regulation principles of small molecules in a high-throughput manner, thus would be very effective for the analysis of drug combinations, especially for TCM preparations. In this work, we have proposed the TCM-Mesh system, which records TCM-related information collected from various resources and could serve for network pharmacology analysis for TCM preparations in a high-throughput manner (http://mesh...

One of the most effective strategies to enhance metabolite biosynthesis and accumulation in biotechnological systems is the use of elicitation processes. This study assesses the influence of different concentrations of yeast extract (YE) on ginsenoside biosynthesis in Panax quinquefolium (American ginseng) hairy roots cultivated in shake flasks and in a nutrient sprinkle bioreactor after 3 and 7 days of elicitation. The saponin content was determined using HPLC. The maximum yield (20 mg g(-1) d.w.) of the sum of six examined ginsenosides (Rb1, Rb2, Rc, Rd, Re and Rg1) in hairy roots cultivated in shake flasks was achieved after application of YE at 50 mg L(-1) concentration and 3 day exposure time...

REVIEW
Hong-Yi Qi, Li Li, Hui Ma
Ginseng, one of the most widely used traditional herbal medicines and dietary supplements, has historically been recognized as a tonic herb and adaptogen that can enhance the body's tolerance to various adversities. Ginsenosides are a diverse group of steroidal saponins that comprise the major secondary metabolites of ginseng and are responsible for its multiple pharmacological effects. Emerging evidence suggests that hormetic phytochemicals produced by environmentally stressed plants can activate the moderate cellular stress response mechanisms at a subtoxic level in humans, which may enhance tolerance against severe dysfunction or disease...

Herbgenomics provides a global platform to explore the genetics and biology of herbs on the genome level. Panax ginseng C.A. Meyer is an important medicinal plant with numerous pharmaceutical effects. Previous reports mainly discussed the transcriptome of ginseng at the organ level. However, based on mass spectrometry imaging analyses, the ginsenosides varied among different tissues. In this work, ginseng root was separated into three tissues-periderm, cortex and stele-each for five duplicates. The chemical analysis and transcriptome analysis were conducted simultaneously...

Panax ginseng is the most widely used herbal medicine for improving cognitive functions. The pharmacological activity and underlying mechanisms of mountain-cultivated ginseng, however, have yet to be clearly elucidated, in particular, against trimethyltin-induced cognitive dysfunction. We previously reported that interleukin-6 plays a protective role against trimethyltin-induced cognitive dysfunction. Because of this, we have implemented a study system that uses interleukin-6 null (-/-) and wild-type mice. Interestingly, mountain-cultivated ginseng significantly upregulated interleukin-6 expression...

Mycotoxins and selected hazardous alkaloids in the medicinal plants (Panax ginseng, Angelica sinensis, and Withania somnifera) and dietary supplements were determined. Purine alkaloids were found in majority of samples; however, isoquinoline alkaloids were less abundant than indole. The predominant alkaloids appear to be caffeine (purine group), harman (indole group) and berberine (isoquinoline). Examined medicinal plants and dietary supplements were contaminated by mycotoxins (especially ochratoxin A 1.72-5...

Ginsenoside is the most important secondary metabolite of ginseng. Natural sources of wild ginseng have been overexploited. Although root culture could reduce the length of the growth cycle of ginseng, the number of ginsenosides is fewer and their contents are lower in adventitious roots of ginseng than that in ginseng cultivated in the field. In this study, we investigated the effects of endophytic bacterial elicitors on biomass and ginsenoside production in adventitious roots cultures of Panax ginseng. Endophyte LB 5-3 as an elicitor could increase biomass and ginsenoside accumulation in ginseng adventitious root culture...

Ginseng represents a set of high-value medicinal plants of different species: Panax ginseng (Asian ginseng), P. quinquefolius (American ginseng), P. notoginseng (Chinese ginseng), P. japonicus (Bamboo ginseng), and P. vietnamensis (Vietnamese ginseng). Each species is pharmacologically and economically important, with differences in efficacy and price. Accordingly, an authentication system is needed to combat economically motivated adulteration of Panax products. We conducted comparative analysis of the chloroplast genome sequences of these five species, identifying 34-124 indels and 141-560 SNPs...
