When ginsenoside Rb1 and Rb2 were anaerobically incubated with human intestinal microflora, these ginsenosides were metabolized to 20-O-beta-D-glucopyranosyl-20(S)-protopanaxadiol (compound K) and 20(S)-protopanaxadiol. Several kinds of intestinal bacteria hydrolyzed these ginsenosides. Eubacterium sp., Streptococcus sp. and Bifidobacterium sp., which more potently
