Abstract: Three new olean-type triterpenoids,3β,15α-dihydroxy-olean-12(13)-en-16-one(1),3β,15α,23-trihydroxy-olean-12(13)-en-16-one (2)and 15α-hydroxy-16-oxo-olean-12-en-3-o-β-glucuro-nopyranoside(3),named eriocarpins A(1),B(2)and C(3),respectively, alongwith two known compounds 2β,3β,28-trihydroxy-12(13)-en-olean and β-amyrin were isolated from the roots of Derris eriocarpa How.Their structures were determined were determined by the basis of chemical and spectral evidences.

Key words: Derris eriocarpa
