    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.

    Four new C-21 steroidal glycosides, mucronatosides E (1), F (2), G (3), and H (4), were isolated from the stems of Stephanotis mucronata. Two of them had the rare aglycone with a double bond between C-6 and C-7. Their structures were elucidated on the basis of spectroscopic data and chemical evidence. These isolated compounds were assayed for their immunological activities in vitro against concanavalin
