New triterpenoids from Corchorus trilocularis.
Two new tetracyclic triterpenoid trilocularol A and trilocularol A 3-glucoside and one pentacyclic triterpenoid tirlocularoside A were isolated from Corchorus trilocularis L., their structure were elucidated as 3beta,6alpha,16alpha,20(S),27-pentahydroxydammar-24(Z)-ene (1), 3beta-D-glucopyranosyloxy-6alpha,16alpha,20(S),27-tetrahydroxydammar-24(Z)-ene (2) and 2alpha,3beta,19alpha,30-tetrahydroxyurs-12-en-24,28-dioic acid 28-O-beta-D-glucopyranosyl ester (3). respectively, on the basis of detailed spectroscopic studies.
