目的 研究许树Clerodendrum inerme的化学成分.方法 利用硅胶柱色谱进行分离和纯化,通过光谱分析鉴定结构.结果 分离到8个化合物,鉴定为木栓酮(friedelin,Ⅰ)、豆甾醇(stigmasterol,Ⅱ)、白桦酸(betulinicacid,Ⅲ)、金合欢素(acacetin,Ⅲ)、丁香酸(syringicacid,Ⅳ)、对甲氧基苯甲酸(Ⅴ)、芹菜素(apigenin,Ⅵ)和胡萝卜苷(daucosterol,Ⅶ).结论 化合物Ⅱ、Ⅲ、Ⅳ、Ⅳ、Ⅶ为首次从该植物中分离得到.

Objective To study the chemical constituents from Clerodendrum inermeMethods The constituents were isolated and repeatedly purified on silica gel column chromatography and their structures were elucidated by spectral analysisResults Eight compounds：friedelin(I),stigmasterol(Ⅱ),betulinic acid(Ⅲ),acacetin(Ⅳ),syringic acid(V),P-methoxybenzoic acid(Ⅵ),apigenin(Ⅶ),and daucosterol(Ⅷ)were isolated from the aerial part of C.inermeConclusion CompoundsⅡ,Ⅲ,V,VI,andⅧare isolated from C.inerme for the first time.
