摘要
目的:研究杜仲叶中的环烯醚萜类成分.方法:采用各种柱色谱方法分离纯化,通过理化常数测定和波谱分析鉴定环烯醚萜类化合物的结构.结果:从杜仲叶中分离纯化了9个环烯醚萜类化合物,分别鉴定为:车叶草苷(1)、交让木苷(2)、鸡屎藤苷甲酯(3)、马钱素(4)、8-表马钱素(5)、7-表马钱素(6)、去乙酰车叶草苷酸甲酯(7)、京尼平苷(8)、京尼平苷酸(9).结论:其中,化合物2~7为首次从该植物中分离得到,化合物4~6为首次从该属植物中分离得到.
Objective:To investigate the chemical constituents of iridoids from Eucommiae Folium. Methods:The compounds were isolated and purified by various column chromatography, the structures were identified on the basis of physiochemical properties and spectral analysis. Results:Nine iridoids were isolated and identified as asperuloside (I), daphylloside (2), scandoside methyl ester(3 ), loganin(4) ,8-epi-loganin ( 5 ), 7-epi-loganiu ( 6 ), deacetyl asperulosidic acid methyl ester ( 7 ), geniposide ( 8 ) and geuiposidic acid (9). Conclusion:Compounds 2 -7 are isolated from this plant for the first time, compounds 4 -6 are isolated from this genus for the first time.
