Ginsenoside Rb1 is the most predominant ginsenoside in Panax species (ginseng) and the hydrolysis of this ginsenoside produces pharmaceutically active compounds. Caulobacter leidyia GP45, one of the isolates having strong β-glucosidase-producing activity, converted ginsenoside Rb1 to the active metabolites by 91%. The structures of the resultant metabolites were identified by NMR. Ginsenoside Rb1 had been consecutively converted to ginsenoside Rd (1), F2 (2) and compound K (3) via the hydrolyses of 20-C β-(1→6)-glucoside, 3-C β-(1→2)-glucoside, and 3-C β-glucose of ginsenoside Rb1.
