Abstract
Abstract Guaiacin, C, D, E and F, four new saponins, have been isolated from the leaves of Guaiacum officinale and characterised on the basis of chemical investigation and spectroscopic studies as 3- O -[α- l -rhamnopyranosyl(1 → 2)α- l -arabinopyranosyl(3 → 1)β- d -glucopyranosyl]-30-norolean-12,20(29)-dien-28-oic acid; 3- O -[α- l -rhamnopyranosyl-(1 → 2)α- l -arabinopyranosyl(3 → 1)β- d -glucopyranosyl]-30-norolean-12,20(29)-dien-28- O -[β- d -glucopyranosyl] ester; 3- O -[β- d -glucopyranosyl(1 → 2)α- l -arabinopyranosyl(3 → 1)β- d -glucopyranosyl]-30-norolean-12,20(29)-dien-28- O -[β- d -glucopyranosyl]ester; 3- O -[β- d -glucopyranosyl(1 → 2)α- l -arabinopyranosyl(3 → 1)β- d -glucopyranosyl] oleanolic acid-28- O -[β- d -glucopyranosyl]ester.
