摘要:
Two new triterpenoid saponins, tanguticoside A and B along with seven known saponins vitalboside B, alpha -hederin, saponin PK, beta -hederin, saponin Pl(3), saponin PE, and ciwujianoside A were isolated from aerial part of Clematis tangutica. By chemical and spectral evidences methods, the structures of tanguticoside A and B were elucidated as 3-O-beta -D-glucopyrano-sylhederagenin 28-O-alpha -L-rhamnopyranosyl-(1 -->4)-beta -D-glucopyranosyl-(1 -->2)-beta -D- -glucopyranoside and 3-O-beta -D-glucopyranosyl-1 -->2)-beta -D-glucopyranosylhederagen in 28-O-alpha -L-rhamnopyranosyl-(1 -->4)-beta -D-glucopyranosyl-(1 -->6)-beta -D-glucopyranoside, respectively.
