On hydrolysis with dilute mineral acid, Ginseng saponins, ginsenosides-Rb_1,-Rb_2,-Rb_3,-Rc, and -Rd yielded panaxadiol (IV), and ginsenosides-Re, -Rf, -Rg_1,and -Rg_2 and 20-glucoginsenoside-Rf afforded panaxatriol (X). The optimal condition of saponinhydrolysis for the quantitative analysis of IV and X was studied. The crude hydrolysates of methanol extract of Ginseng were trimethylsilylated with N-trimethylsilylimidazole and the saponin content was calibrated by the gas chromatographic determination of TMS-panaxadiol and TMS-panaxatriol, using diacetylhederagenin methyl ester as the internal standard. This procedure was applied to the evaluation of the commercial "Ginseng Tea" and "Ginseng Extract."
