英文摘要:

Four new triterpenoid saponins, designated as stelmatotriterpenosides E-H (1-4), together with three known compounds, asterbatanoside B (5), 2alpha;3beta,19alpha;23-tetrahydroxy-olean-12-en-28-oic acid-3-O-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosyl ester (6) and 2alpha,3beta,19alpha,23-tetrahydroxy-urs-12-en-28-oic acid-3-O-beta-D-glucopyranosyl-28-0-p-D-glucopyranosyl ester (7), were isolated from the stems of Stelmatocrypton khasianum. On the basis of chemical and spectral evidence, the structures of 1-4 were established as 2alpha,3beta,23-trihydroxyolean-12-en-28-oic acid-3-O-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester (1), 2alpha,3beta,23-trihydroxy-urs-12-en-28-oic acid-3-O-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester (2), 2alpha,3beta,19alpha-trihydroxy-urs-12-en-28-oic acid-3-O-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl ester (3), and 2alpha,3beta,19alpha-trihydroxy-urs-12-en-24,28-dioic acid-24-O-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosyl diester (4).
