Two new saponins, gymnemic acid-VIII and -IX, were isolated from the water extract of leaves of Gymnema sylvestre R. Br. along with three known saponins, gymnemic acid III, IV, and V. Their structures, clarified on the basis of spectroscopic and chemical means, present rare examples of a hexulopyranoside moiety at 0-3’ on gymnemic acid-III and -IV, respectively.
