摘要
目的:研究白花败酱的化学成分。方法:采用硅胶柱层析、Sephadex LH-20等色谱方法进行分离纯化,依据理化性质及波谱数据进行结构鉴定。结果:从白花败酱乙醇提取物中分离得到6个化合物,分别鉴定为:8,9-didehydro-7-hydroxydolichodial-1-dimethyl acetal(1)、8,9-didehydro-7-hydroxydolichodial(2)、熊果酸(3)、3-O-甲基槲皮素(4)、木犀草素(5)、山柰酚-3-O-阿拉伯糖苷(6)。结论:其中,化合物1为新裂环环烯醚萜,化合物2、4、6为首次从败酱属植物中分离得到。
Objective: To investigate the chemical constituents from the ethanol extract of Patrinia villosa. Methods: Various column chromatographic methods including silica gel and Sephadex LH-20 were used for the isolation and purification. Chemical structures were elucidated on the basis of spectroscopic analysis. Results: Six compounds were isolated and identified as 8,9-didehydro-7-hydroxydolichodial-1-dimethyl acetal( 1),8,9-didehydro-7-hydroxydolichodial( 2),ursolic acid( 3),3-O-methylquercetin( 4),luteolin( 5) and kaempferol-3-O-arabinoside( 6). Conclusion: Compound 1 is a new secoiridoid,and compounds 2,4,6 are isolated from the Patrinia genus for the first time.
