Ginsenoside Rb1is the main component in ginsenosides. It is a protopanaxadiol-type ginsenoside that has a dammarane-type triterpenoid as an aglycone. In this study, ginsenoside Rb1 was transformed into gypenoside XVII, ginsenoside Rd, ginsenoside F2 and compound K by glycosidase from Leuconostoc mesenteroides DC102. The optimum time for the conversion was about 72 h at a constant pH of 6.0 to 8.0 and the optimum temperature was about 30â. Under optimal conditions, ginsenoside Rb1 was decomposed and converted into compound K by 72 h post-reaction (99%). The enzymatic reaction was analyzed by highperformance liquid chromatography, suggesting the transformation pathway: ginsenoside Rb1â gypenoside XVII and ginsenoside Rdâginsenoside F2âcompound K.
