海南冬青的化学成分研究

Studies on Chemical Constituents of Ilex hainanensis Merr.

目的：进一步阐明海南冬青的化学成分。方法：理化性质和光谱数据鉴定。结果：分离得到４个化合物，为乌索酸，冬青素Ａ，冬青皂甙Ａ１和胡萝卜甙。结论：均为首次从该植物中分得。

Objective:To further probe into the chemical composition of Ilex hainanensis.Method:Compound isolation was affected on the basis of the EtOAc soluble fraction of the ethanolic extract from the leaves of the plant.Result:Four compounds were obtained and by physico chemical and spectroscopic methods identified as ursolic acid,ilexgenin A,ilexsaponin A l and β sitosterol 3 O β D glucoside.Conclusion:All the four compounds were isolated from the plant for the first time.
