摘　　要：目的:研究天胡荽的化学成分。方法:采用硅胶柱色谱、Sephadex LH-20凝胶色谱MCI柱色谱及结晶、重结晶的方法进行分离纯化天胡荽各成,并运用波谱方法对所分得的化合物进行结构鉴定。结果:从天胡荽中分得了8个化合物,分别鉴定为槲皮素(quercetin)、芹菜素(apigenin)、山奈酚(kaempferol)、β-谷甾醇(β-sitosterol)、菠甾醇(α-spinasterol)、牡荆苷(vitexin)、异牡荆苷(isovitexin)以及胡萝卜苷(β-daucosterol)。结论:化合物5~7为首次从天胡荽中分离得到。Objective： To study the chemical constituents of Hydrocotyle sibthorpioides. Methods：The constituents of Hydrocotyle sibthorpioides were separated by column chromatography,crystallization and recrystallization,and their structures were elucidated by spectroscophic means. Results： Eight compounds were isolated from the leaves of Hydrocotyle sibthorpioides and identified as quercetin（ 1）,apigenin（ 2）,kaempferol（ 3）,β-sitosterol（ 4）,α-spinasterol（ 5）,vitexin（ 6）,isovitexin（ 7） and β-daucosterol（ 8）. Conclusion： Compounds 5-7 are obtained from Hydrocotyle sibthorpioides for the first time.
