A new triterpenoid, 2α-,3β-,19α-trihydroxy-urs-12-ene-24,28-dioic acid (1), along with two known compounds, 3β-acetoxy-urs-12-ene-11-one (2) and vomifoliol (3), was isolated from stems of Stelmatocrypton khasianum for the first time. Their structures were elucidated on the basis of chemical and spectroscopic methods.
