Biotransformation of major ginsenosides in ginsenoside model culture by lactic acid bacteria

Some differences have been reported in the biotransformation of ginsenosides, probably due to the types of materials used such as ginseng, enzymes, and microorganisms. Moreover, most microorganisms used for transforming ginsenosides do not meet food-grade standards. We investigated the statistical conversion rate of major ginsenosides in ginsenosides model culture (GMC) during fermentation by lactic acid bacteria (LAB) in order to estimate possible pathways.

Rapid characterization of ginsenosides in the roots and rhizomes of by UPLC−DAD−QTOF−MS/MS and simultaneous determination of 19 ginsenosides by HPLC–ESI–MS

Ginsenosides are the characteristic and principal components which manifest a variety of the biological and pharmacological activities of the roots and rhizomes of Panax ginseng (GRR). This study was carried out to qualitatively and quantitatively determine the ginsenosides in the cultivated and forest GRR.

Development of a SNP Marker for Specific Authentication of Korean ginseng’s ( Meyer) New cultivar “G-1”

Korean ginseng (Panax ginseng) one of the well-known medicinal plant of Oriental medicine that is still in practice. A total of 11 Korean ginseng cultivars with unique features to Korean ginseng have been developed until now based on pure line selection method. Among them, a new cultivar namely G-1 with different agricultural traits related to yield and content of ginsenosides was developed in 2012.

Microbial conversion of major ginsenosides in ginseng total saponins by endophytes

In this study, we screened and identified an endophyte JG09 having strong biocatalytic activity for ginsenosides from Platycodon grandiflorum (P. grandiflorum), converted ginseng total saponins and ginsenoside monomers, determined the source of minor ginsenosides and the transformation pathways, and calculated the maximum production of minor ginsenosides for the conversion of ginsenoside Rb1 to assess the transformation activity of endophyte JG09.

Determination of ginsenosides in Asian and American Ginsengs by liquid chromatography-quadrupole/time of flight-mass spectrometry: assessing variations based on morphological characteristics

Asian ginseng and American ginseng are functional food that share a close genetic relationship and are well-known worldwide. This article aims to investigate the correlation between morphological characteristics and the inherent quality of Asian and American ginsengs.

Animal lectins: potential receptors for ginseng polysaccharides

Panax ginseng Meyer, belonging to the genus Panax of the family Araliaceae, is known for its human immune system-related effects such as immune-boosting effects. Ginseng polysaccharides (GPs) are the responsible ingredient of ginseng in immunomodulation, which are classified as acidic and neutral GPs. Although GPs participate in various immune reactions including the stimulation of immune cells and production of cytokines, the precise function of GPs together with its potential receptor(s) and their signal transduction pathways have remained largely unknown.

Ginsenoside Rg1 suppresses early stage of adipocyte development via activation of CHOP10 in 3T3-L1 and attenuates fat accumulation in high fat diet-induced obese zebrafish

Ginsenoside Rg1 is a class of steroid glycoside and triterpene saponin in Panax ginseng. Many studies suggest that Rg1 suppress adipocyte differentiation in 3T3-L1. However, the detail molecular mechanism of Rg1 on adipogenesis in 3T3-L1 has still not been fully understood yet.
