Abstract
Three new pregnane glycosides (S-4a, S-5 and S-10) and two known pregnane glycosides (S-4b and S-6) were isolated from an antitumour fraction of the root barks of Periploca sepium. Their structures were determined by 1H and 13C NMR, FABMS and SIMS spectroscopy and some chemical transformations. One of the glycosides (S-4a) contained the new aglycone Δ5-pregnene-3β,16β,20(R)-triol.
