OBJECTIVE
We investigated the pharmacological effects of saponins isolated from ginseng root and their metabolites, which occur by hydrolysis of the sugar moieties connecting the aglycone of saponins in the digestive tract, on the production of corticosteroids in bovine adrenal fasciculata cells in

A previous study demonstrated that ginseng crude saponins prevent obesity induced by a high-fat diet in rats. Ginseng crude saponins are known to contain a variety of bioactive saponins. The present study investigated and compared the antiobesity activity of protopanaxadiol (PD) and protopanaxatriol

Ginsenosides are responsible for diverse pharmacological properties ascribed to ginseng, a plant used in traditional medicine. Ginsenosides are classified into three categories: Protopanaxadiol, protopanaxatriol (PPT) and oleanolic acid. As an aglycone of PPT-type ginsenosides, PPT exists in two
Complete biotransformation of protopanaxatriol-type ginsenosides in Panax ginseng leaf extract to aglycon protopanaxatriol by β-glycosidases from Dictyoglomus turgidum and Pyrococcus furiosus.
