✦ Synopsis

Abstract

A new polyoxygenated pregnane genin and a new diphenylmethane, along with five known pregnane derivatives, were isolated from the root barks of Periploca sepium. The structures of the new compounds were elucidated as (3__β__,14__β__)‐3,14‐dihydroxy‐21‐methoxypregn‐5‐en‐20‐one (1) and 2‐hydroxy‐5‐(2‐hydroxy‐4‐methoxybenzyl)‐4‐methoxybenzaldehyde (2) on the basis of spectroscopic methods, especially 2D‐NMR and MS analyses. The known compounds were identified by comparing their physical and spectroscopic data with those reported in the literature.
