Abstract Augustic acid, a new oleanane derivative, and a stigmasterol glycoside were isolated from the roots of Ambroma augusta. Their structures were established as olean-12-en-2β,3β-diol-28-oic acid and stigmast-5,22-dien -3-O-α- d -glucopyranoside respectively, on the basis of full spectral analyses and chemical methods.
