摘　　要：从滇杠柳(Periploca forrestii)根茎中分得一个新强心甙元8-羟基杠柳甙元(3β,5β,8β,14β-四羟基-强心甾-20(22)-烯内酯(1),同时还获得杠柳甙元(2),杠柳甙(3),北五加皮甙E(4),胡萝卜甙(5)和熊果酸(6)。它们的化学结构经光谱和化学方法得以确定。A novel cardenolide (1 ) and five known compounds (2- 6) were isolated from the acetone soluble fraction of the alcohol extract of rhizome of Penploca forrestii by means of column chromalography. The structures were established as 8-hydroxy-periplogenin (3β, 5β, 8β, 14β-tetrahydroxy-card-20(22) -enolide) ( 1 ), periplogenin( 2 ), periplocin( 3 ) , glycoside E of Pcriploca sepium (△5-pregnene-3β, 17α, 20α-triol-20-O-β-D-canaropyranoside) ( 4 ), daucosterol( 5 ) and ursolic acid( 6 )respectively on the basis of UV, IK, MS, high resolution NMK analyses and chemical evidences.
