Glycosylation of natural compounds increases the diversity of secondary metabolites. Glycosylation steps are implicated not only in plant growth and development, but also in plant defense responses. Although the activities of uridine-dependent glycosyltransferases (UGTs) have long been recognized, and genes encoding them in several higher plants have been identified, the specific functions of UGTs in planta remain largely unknown.

Effect of high-dose ginsenoside complex (UG0712) supplementation on physical performance of healthy adults during a 12-week supervised exercise program: A randomized placebo-controlled clinical trial
Ginseng has been used as an ergogenic agent, although evidence for its effectiveness is weak. A randomized, double-blind, placebo-controlled clinical trial was conducted to evaluate the effect of a ginsenoside complex (UG0712) on changes in exercise performance.
Ginsenoside Rg1 modulates medial prefrontal cortical firing and suppresses the hippocampo-medial prefrontal cortical long-term potentiation
Panax ginseng is one of the most commonly used medicinal herbs worldwide for a variety of therapeutic properties including neurocognitive effects. Ginsenoside Rg1 is one of the most abundant active chemical constituents of this herb with known neuroprotective, anxiolytic and cognition improving effects.
The comparative study on chemical composition of the total saponins extraction from fermented and white ginseng under the effect of macrophages phagocytotic function
In this study, we adopt the white ginseng as raw material, which was processed as fermented ginseng products with Paecilomyces hepiali through solid culture. The characteristic chemical markers of them were investigated by RRLC–Q-TOF-MS (rapid resolution liquid chromatography coupled with quadrupole time -of-flight mass spectromtry) method combined with multivariate statistical analysis.And the implications of these components on biological activity were investigated for the improvement of the phagocytic function of macrophages in Zebrafish.According to the established RRLC–QTOF-MS chemical profiling, the contents in ginsenosides of high molecular weight especially malonylated protopanaxadiol ginsenosides were slightly decrease due to the fermentation process, which were hydrolyzed into rare and minor ginsenosides.
Korean Red Ginseng extract reduces hypoxia-induced epithelial-mesenchymal transition by repressing NF-κB and ERK1/2 pathways in colon cancer
The incidence of colorectal cancer (CRC) is increasing, with metastasis of newly diagnosed CRC reported in a large proportion of patients. However, the effect of Korean Red Ginseng extracts (KRGE) on epithelial to mesenchymal transition (EMT) in CRC is unknown. Therefore, we examined the mechanisms by which KRGE regulates EMT of CRC in hypoxic conditions.
The skin protective effects of compound K, a metabolite of ginsenoside Rb1 from
Compound K (CK) is a ginsenoside, which is a metabolite of Panax ginseng. There is interest both in increasing skin health and anti-aging using natural skin care products. In this study, we explored the possibility of using CK as a cosmetic ingredient.
Study on the grading standard of seedlings
The quality differences in seedlings of medicinal herbs often affect the quality of medicinal parts. The establishment of the grading standard of Panax notoginseng (P. notoginseng) seedlings is significant to the stable quality of medicinal parts of P. notoginseng.
The melanogenesis inhibition activity of floralginsenoside A from
Panax ginseng is a traditional herb used for medicinal purposes in eastern Asia. P. ginseng contains various ginsenosides with pharmacological effects. In this study, floralginsenoside A (FGA), ginsenoside Rd (GRD), and ginsensoside Re (GRE) were purified from P. ginseng.
New metabolites from the biotransformation of ginsenoside Rb1 by sp.229 and activities in inducing osteogenic differentiation by Wnt/β-catenin signaling activation
Ginseng is a well-known traditional Chinese medicine that has been widely used in a range of therapeutic and health-care applications in East Asian countries. Microbial transformation is regarded as an effective and useful technology in modification of nature products for finding new chemical derivatives with potent bioactivities. In this study, three minor derivatives of ginsenoside compound K were isolated and the inducing effects in Wnt signaling pathway were also investigated.
Quality and Characteristics of Fermented Ginseng Seed Oil based on Bacterial Strain and Extraction Method
In this study, the fermentation of ginseng seeds was hypothesized to produce useful physiologically-active substances, similar to that observed for fermented ginseng root. Ginseng seed was fermented using Bacillus, Pediococcus, and Lactobacillus strains to extract ginseng seed oil, and the extraction yield, color, and quantity of phenolic compounds, fatty acids, and phytosterol were then analyzed.
