铁甲草化学成分的初步研究

Chemical Constituents of Cassia mimosoides Linn.

采用硅胶柱色谱分离方法,研究了铁甲草(Cassiami mosoides Linn.)乙醇提取物中的化学成分。从铁甲草中分离得到8个化合物:大黄素(1)、木犀草素(2)、间苯二酚(3)、齐墩果酸(4)、(R)-鹰爪三醇(5)、α-L-鼠李糖(6)、β-谷甾醇(7)和胡萝卜苷(8)。除化合物1以外,其余均是首次从铁甲草中分离得到,其中化合物5为首次在该科植物中发现。

Eigth compounds were isolated from the ethanol extraction of Cassia mimosoides Linn. using by menthod of silica gel column and chromatograghy separation. On the basis of spectral data, they were identified as emodin （1）, luteolin （2）, 1,3-benzenediol （3）, oleanolic acid （4）, （R）-artabotriol （5）, α-L-rhamnose （6）, β-sitosterol （7） and daucosterol （8）. All compounds except 1 were isolated from this plant for the first time, and compound 5 was obtained from Leguminosae for the first time.
