The 20-O-multi-glycoside ginsenosidase catalyses the hydrolysis of the 20-O-alpha-(1->6)-glycosidic bond and the 20-O-beta-(1->6)-glycosidic bond of protopanaxadiol-type ginsenosides. The enzyme usually leaves a single glucosyl residue attached at position 20, although it can cleave the remaining glucosyl residue with a lower efficiency. Starting with a ginsenoside that is glycosylated at positions 3 and 20, such as ginsenosides Rb1, Rb2, Rb3 and Rc, the most common product is ginsenoside Rd, with a low amount of ginsenoside Rg3 also formed.

ginsenosidase type V enzymes hydrolyze the sugars linked to C-20 and C-6 in the PPD-type ginsenosides with the hydrolysis patterns of B, E and F. Crude enzyme from Penicillium sp. and beta-glucosidase from Actinosynnema mirum convert ginsenosides Re and Rg1 to Rh1 and APPT, respectively
ginsenosidase type II does not hydrolyze the 3-O-beta-glucoside of Rb1, Rb2, Rb3. Ginsenosidase type II does not hydrolyze the glycosides of protopanaxatriol type ginsenoside such as Re, Rf, Rg1
