摘要
Two new saponins were isolated from the leaves of Panax quinquefolium and their structures were elucidated as 3, 6, 20S-trihydroxy-12, 23R-epoxydammar-24-ene 6-O-[-L-rhamnosyl(12)--D-glucopyranosyl]-20-O--D-glucopyranoside (1) and 3, 20S-dihydroxy-12, 23R-epoxydammar-24-ene 3-O-[-D-glucopyranosyl(12)--D-glucopyranosyl]-20-O--D-glucopyranoside (2) on the basis of physicochemical evidence.
