Triterpenoid Derivatives from Cylicodiscus gabunensis

Abstract

Three new olean-12-ene derivatives (1—3), together with known urs-12-ene-3β, 28-diol (4) were isolated from the stem root of Cylicodiscus gabunensis. The structures of the new compounds were established by chemical and spectroscopic means as β-amyrin-n-nonyl ether (1), 22α-hydroxyolean-12-en-3β-yl-β-D-galactopyranoside (2), and 24-hydroxyolean-12-en-3β-yl-β-D-glucopyranoside (3).
