Abstract: Three new polyhydroxylatedtriterpenes were isolated from the chloroform-methanol extract of the leaves of Seneciopseudotites. Their structures were elucidated as 2α,3β,23-trihydroxy-urs-12,19(29)-dien-28-oic-acid; 2α,3β,23-trihydroxy-urs-12,19(29)-dien-28-oic-acid-23-acetyl ester; 23-(trans-p-coumaroyloxy)-2α,3β-dihydroxy-urs-12,19(29)-dien-28-oic-acid by NMR spectroscopy.
