Abstract
An extensive investigation of the so-called jalapin resinoid obtained from roots of the Mexican scammony, Ipomoea orizabensis, using high field NMR sp ectroscopy led to the characterization of six glycosides, including the kno wn scammonins I (1) and II (2) and four new tetrasaccharides of jalapinolic acid, orizabins V-VIII (3-6). All the isolates (1-6) were found to be weak ly cytotoxic toward human oral epidermoid carcinoma (KB).
