Triterpenoid derivatives from Cylicodiscus gabunensis.
Three new olean-12-ene derivatives (1-3), together with known urs-12-ene-3beta, 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 beta-amyrin-n-nonyl ether (1), 22alpha-hydroxyolean-12-en-3beta-yl-beta-D-galactopyranoside (2), and 24-hydroxyolean-12-en-3beta-yl-beta-D-glucopyranoside (3).
