Lignans Related to Olivil from Genus Cerbera (Cerbera. VI)

Abstract

Three olivil dimers, 5’,5’’#x2019;-bis-olivil, 5’,5’’-bis-olivil, and 5,5’’-bis-olivil, were isolated from the stems of Cerbera manghas and C. odollam together with (–)-olivil and (+)-cycloolivil, and their structures were determined on the basis of spectral evidence. Olivil 4-0-glucoside and 4’-O-glucoside were also obtained from the leaves of C. manghas. © 1988, The Pharmaceutical Society of Japan. All rights reserved.
