Enzymatic transformation of the major ginsenoside Rb2 to minor compound Y and compound K by a ginsenoside-hydrolyzing β-glycosidase from Microbacterium esteraromaticum

Journal of Industrial Microbiology and Biotechnology, 2012
Abstract The ginsenoside-hydrolyzing β-glycosidase (Bgp3) derived from Microbacterium esteraromaticum transformed the major ginsenoside Rb2 to more pharmacologically active minor ginsenosides including compounds Y and K. The bgp3 gene consists of 2,271 bp encoding 756 amino acids which have homology to the glycosyl hydrolase family 3 ...

Identification of mountain-cultivated ginseng and cultivated ginseng using UPLC/oa-TOF MSE with a multivariate statistical sample-profiling strategy

Journal of Ginseng Research, 2016
Background: Mountain-cultivated ginseng (MCG) and cultivated ginseng (CG) both belong to Panax ginseng and have similar ingredients. However, their pharmacological activities are different due to their significantly different growth environments. Methods:

Enhanced Production of Gypenoside LXXV Using a Novel Ginsenoside-Transforming β-Glucosidase from Ginseng-Cultivating Soil Bacteria and Its Anti-Cancer Property

Molecules, 2017
Minor ginsenosides, such as compound K, Rg3(S), which can be produced by deglycosylation of ginsenosides Rb1, showed strong anti-cancer effects. However, the anticancer effects of gypenoside LXXV, which is one of the deglycosylated shapes of ginsenoside ...

Co-transformation of Panax major ginsenosides Rb1 and Rg1 to minor ginsenosides C–K and F1 by Cladosporium cladosporioides

Journal of Industrial Microbiology and Biotechnology, 2012
Abstract Rb1 and Rg1 are the major ginsenosides in protopanaxadiol and protopanaxatriol. Their content in ginsenosides was 23.8 and 17.6%, respectively. A total of 22 isolates of β-glucosidase producing microorganisms were isolated from the soil of a ginseng field using Esculin-R2A agar.

Microbial conversion of major ginsenoside Rb1 to minor ginsenoside Rd by Indian fermented food bacteria

African Journal of Biotechnology, 2011
Ginsenoside Rb1 is the predominant secondary metabolite (saponin) in Panax ginseng. Hydrolysis of the sugar residues in Rb1 yields more pharmaceutically active ginsenosides like Rd, Rg3, F2, Rh2 andC-K. Among them, the minor ginsenoside Rd enhances the differentiation of neural stem cells, protects neurons from neurotoxic chemicals, decreases urea ...

Enzymatic formation of compound-K from ginsenoside Rb1 by enzyme preparation from cultured mycelia of Armillaria mellea

Journal of Ginseng Research, 2016
Background: Minor saponins or human intestinal bacterial metabolites, such as ginsenosides Rg3, F2, Rh2, and compound K, are more pharmacologically active than major saponins, such as ginsenosides Rb1, Rb2, and Rc.
