细茎银莲花的化学成分

目的 对细茎银莲花（Anemone rossii Moore）根茎的化学成分进行初步研究。方法 细茎银莲花根茎以体积分数为75%的乙醇提取，提取物经系统溶剂萃取，对其氯仿萃取部分进行反复柱色谱分离，利用理化性质和波谱分析进行结构鉴定。 结果 从细茎银莲花根茎中分离得到7个已知化合物，分别为桦皮醇（1）、桦皮酸 （2）、齐墩果酸（3）、β-谷甾醇（4）、香豆素 （5）、4，7-二甲氧基-5-甲基香豆素 （6）、齐墩果酸-3-O-α-L-吡喃阿拉伯糖苷（7）。结论 所有化合物均为首次从细茎银莲花中分离得到。

Chemical constituens of Anemone rossii Moore

Aim To study the chemical constitutents from rhizome of Anemone rossii. Method The rhizome of the plant were extracted with 75% ethanol, the ethanol extract was extracted then with petroleum ether, chloroform, ethyl acetate and n-butanol respectively. The chloroform extraction was submitted to chromatography on silica gel column and seven compounds were isolated. Their structures were elucidated on the basis of physical-chemical method, spectral analysis and by comparison with certain authentic samples. Result The isolated compounds were identified as betulin (1), betulic acid (2), oleanolic acid (3), β-sitosterol (4), coumarin (5), 4,7-dimethoxyl-5-methyl-coumarin (6) , and oleanolic acid-3-O-α-L-arabinopyranoside (7)。Conclusion All these compounds are isolated from Anemone rossii Moore for the first time.
