Abstract

Three new triterpene acids were isolated from the twigs and leaves of Hedyotis lawsoniae, together with sixteen known ones. The new compounds were determined to be 3β, 23-dihydroxyurs-12-en-28-oic acid, 3β, 24-dihydroxyurs-12-en-28-oic acid, and 2α, 3β, 24-trihydroxyurs-12-en-28-oic acid on the basis of spectroscopic evidence.
