TRITERPENOIDS AND A TRITERPENE GLYCOSIDE FROM SCHEFFLERA-BODINIERI LEAVES

Two novel triterpenoids and a triterpene glycoside have been isolated from the leaves of Schefflera bodinieri. They are 3-oxo-20-demethyliso aleuritolic-14(15)-ene-28, 29-dioic acid, 28-O-[alpha-L-rhamnopyranosy l ( 1 --> 4)-O-beta-D-glucopyranosyl(1 --> 6)-]-O-beta-D-glucopyranosi de of oxo-20-demethylisoaleuritic-14(15)-ene-28,29-dioic acid and 3 -h ydroxyl-20-demethylisoaleuritolic-l4(15)-ene-28, 30-dioic acid. The kn own compounds, D-sorbitol, stigmsasterol-3-O-beta-D-glucose and two tr isaccharides, were also isolated from the leaves. The structures were established on the basis of chemical and spectral evidence. Copyright (C) 1996 Elsevier Science Ltd
