Herein, a novel ginsenosidase, named ginsenosidase type IV, hydrolyzing 6-O-multi-glycosides of protopanaxatrioltype ginsenosides (PPT), such as Re, R1, Rf, and Rg2, was isolated from the Aspergillus sp. 39g strain, purified, and characterized. Ginsenosidase type IV was able to hydrolyze the 6-O-alpha-L-(1-->2)-rhamnoside of Re and the 6-O-beta-D- (1-->2)-xyloside of R1 into ginsenoside Rg1. Subsequently, it could hydrolyze the 6-O-beta-D-glucoside of Rg1 into F1. Similarly, it was able to… CONTINUE READING
