从滇杠柳(Periploca forrestii)根茎中分得两个新强心甾内酯滇杠柳苷元A(periforgenin A)(Ia)和滇杠柳苷I(periforoside I)(2a)它们具有罕见的变形C/D环甾体骨架。化学结构分别为3β,5β-二羟基-15(14→8)abeo-(8S)-14-酮-强心甾-20(22)-烯内酯和滇杠柳苷元A3-O-β-D-葡葡吡喃糖基(1→4)-β-D-磁麻吡喃糖苷。结构鉴定采用光谱分析及化学方法。1a的结构还经X衍射予以证实。

Two new cardenolides periforgenin A (I) and periforoside I (II) were isolated from the rhizome of P. forrestii collected in Kunming, China, and their structures were established on the basis of spectral and chem. evidences. The structure of I was confirmed by x-ray diffraction anal.
