Seven triterpenoids, i.e., 3β-[(α-l-arabinopyranosyl)oxy]-19β-hydroxyurs-12,20(30)-dien-28-oic acid (1), 3β-[(α-l-arabinopyranosyl)oxy]-urs-11,13(18)-dien-28-oic acid β-d-glucopyranosyl ester (2), 2α,3α,23-trihydroxyurs-12-en-24,28-dioic acid 28-β-d-glucopyranosyl ester (3), 3β-[(α-l-arabinopyranosyl)oxy]-urs-12,19(20)-dien-28-oic acid (4), 3β-[(α-l-arabinopyranosyl)oxy]-urs-12,19(29)-dien-28-oic acid (5), 3β-[(α-l-arabinopyranosyl)oxy]-19α-hydroxyolean-12-en-28-oic acid (6), 2α,3β-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.
