[New triterpenoid glycosides from Dipsacus asper Wall].
Two new triterpenoid glycosides were isolated from the ethanol extracts of roots of Dipsacus asper (Wall). Their structures were deduced as 3-O-beta-D-glucopyranosyl (1----3)-alpha-L-rhamnopyranosyl (1----2)-alpha-L-arabinopyranosyl hederagenin 28-O-beta-D-glucopyranosyl (1----6)-beta-D-glucopyranosyl ester (VII) and 3-O-alpha-L-rhamnopyranosyl (1----3)-beta-D-glucopyranosyl (1----3)-alpha-L-rhamnopyranosyl (1----2)-alpha-L-arabinopyranosyl hederagenin 28-O-beta-glucopyranosyl (1----6)-beta-D-glucopyranosyl ester (VIII), based on spectral analysis and chemical evidences as well as results of 2D-HPTLC.
