ABSTRACT
Objective To systematically investigate the chemical constituents of the roots of Panaxginseng. Methods Mild cold-soaked extraction by 70% aqueous ethanol, successive solvent extraction by ethyl acetate and n-butanol, column chromatography by D101 macroporous absorption resin and reversed-phase silica gel, and semi-preparative HPLC, were used for compounds isolation and purification, while high-resolution mass spectrometry, 1D and 2D NMR data were analyzed for compounds identification. Results A new oleanolic acid tetraglycoside (1) and 19 known ginsenosides (2-20) were isolated and identified. Compound 1 was identified as oleanolic acid 3-O-[β-D-glucopyranosyl-(1→2)-β-D-glucuronopyranosyl]-28-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside, named ginsenoside Ro1 (1). The 19 known ginsenosides were notoginsenoside FP1 (2), ginsenoside Re3 (3), notoginsenoside Rt (4), 20-O-glucosyl ginsenoside Rf (5), ginsenoside Re2 (6), ginsenoside Rg2 (7), ginsenoside Ra2 (8), ginsenoside Rb1 (9), ginsenoside Rc (10), ginsenoside Ra1 (11), malonylginsenoside Rb1 (12), malonylfloralginsenoside Rd5 (13), malonylginsenoside Rc (14), ginsenoside Ro (15), ginsenoside Rd (16), ginsenoside F2 (17), 20(R)-ginsenoside Rh2 (18), ginsenoside F3 (19) and ginsenoside F1 (20). Conclusion Compound1is a new compound. Compound 2, notoginsenoside FP1, is isolated from this plant for the first time.
