Triterpenoids from Sanguisorba officinalis.
Seven triterpenoids, i.e., 3beta-[(alpha-L-arabinopyranosyl)oxy]-19beta-hydroxyurs-12,20(30)-dien-28-oic acid (1), 3beta-[(alpha-L-arabinopyranosyl)oxy]-urs-11,13(18)-dien-28-oic acid beta-D-glucopyranosyl ester (2), 2alpha,3alpha,23-trihydroxyurs-12-en-24,28-dioic acid 28-beta-D-glucopyranosyl ester (3), 3beta-[(alpha-L-arabinopyranosyl)oxy]-urs-12,19(20)-dien-28-oic acid (4), 3beta-[(alpha-L-arabinopyranosyl)oxy]-urs-12,19(29)-dien-28-oic acid (5), 3beta-[(alpha-L-arabinopyranosyl)oxy]-19alpha-hydroxyolean-12-en-28-oic acid (6), 2alpha,3beta-dihydroxy-28-norurs-12,17,19(20),21-tetraen-23-oic cid (7), together with three known ones (8-10), were isolated from the roots of Sanguisorba officinalis. Their structures were determined by spectroscopic and chemical methods. Compounds 7 and 10 showed marginal inhibition activity against the growth of tumor cell lines.
