Two new polyhydroxypregnane glycosides, namely cynotophyllosides I-J, were isolated from the roots of Cynan-chum otophyllum, together with three known steroids, namely deacetylmetaplexigenin, sarcostin and hemoside. Their structures were established by extensive spectroscopic methods especially 2D NMR techniques) and acid-catalysed hydrolysis.
