3-O-Sulfo-triterpenoid Saponins from Gypsophila trichotoma Wend

Abstract

Three new sulfated oleanane-type saponins were isolated from the roots of Gypsophila trichotoma Wend. (Caryophyllaceae). Their structures were established as 3-O-sulfoechinocystic acid 28-β -glucopyranosyl ester (1), 3-O-sulfooleanolic acid 28-β -glucopyranosyl ester (2) and 3-Osulfoquillaic acid 28-β -glucopyranosyl ester (3) on the basis of chemical and spectral evidences.
