Four new pregnane glycosides and a known pregnane glycoside (named periplocoside D, E, L, M, and N, respectively), as well as a steroidal compound S-20, have been isolated from the antitumor fraction of Periploca sepium (Asclepiadaceae). Their structures were established by chemical and spectroscopic methods. S-20 was obtained from this plant for the first time.
