摘　　要：目的:对赶山鞭的化学成分进行分析。方法:用色谱技术分离,根据理化性质和IR,NMR,MS等光谱技术鉴定化合物结构。结果:分离并鉴定出9个化合物。分别为4-羟基苯甲酸(1),6,9-dihydroxy-4,7-megastigmadien-3-one(2),丁醇-O-α-D-果糖苷(3),24-ethyl-cholest-7-ene-3β,5α,6-βtriol(4),已醇(5),1β,6α-二羟基桉烷-4(14)-烯(6),β-谷甾醇(7),5,5-二甲基-4-羟基-四氢呋喃-2-酮(8),β-胡萝卜苷(9)。结论:均为首次从该植物中分到。Objective： To study the constituents of Hypericum attenuatum. Method： The compounds were isolated by chromatography on silica gel, the structures were identified by their physical, chemical properties and IR, NMR and MS spectral data respectively. Result： Nine compounds were isolated and identified as p-hydroxybenzoic acid （1）, 6, 9-dihydroxy-4, 7-megastigmadien-3-one （2）, butyl alcohol-O-α-D-fructoside （3）, 24-ethyl-cholest-7-ene-3β,5α,6β-thtroil （4）, hexanol （5）, 1 β, 6 α-dihydroxyeudesmane-4（14）-ene （6）, β-sitosterol （7）, 5, 5-dimethyl-4-hydroxy-tetrahydrofuran-2-one （8）, β-daucosteml （9）. Conclusion： All of the compounds were isolated from H. attenaatum for the first time.
