摘要
目的:研究杜仲叶中的苯丙素类化学成分。方法:采用各种柱色谱方法分离纯化,通过理化常数测定和光谱分析鉴定化合物结构。结果:从杜仲叶中分离鉴定了9个苯丙素类化合物,分别为:咖啡酸(1)、绿原酸甲酯(2)、紫丁香苷(3)、愈创木基丙三醇(4)、5-甲氧基-愈创木基丙三醇(5)、5,9-二甲氧基-愈创木基丙三醇(6)、9-正丁基-愈创木基丙三醇(7)、9-正丁基-异愈创木基丙三醇(8)、8'-甲氧基-橄榄素(9)。结论:其中,化合物5-9为首次从该植物中分离得到。
Objective:To investigate phenylpropanoids constituents from Eucommia ulmoides leaves. Methods:Various column chromatographic methods were used in isolation and purification. Physiochemical constant determination and spectral analysis were adopted to determine the chemical structures of phenylpropanoids. Results : Nine phenylpropanoids were isolated and identified as caffeic acid ( 1 ), chlorogenic acid methylester ( 2 ), syringin ( 3 ), guaiacylglycerol ( 4 ), 5 -methoxy-guaiacylglycerol ( 5 ), 5,9-dimethoxy-guaiacylglyc- erol ( 6 ) , 9-n-butyl-guaiacylglycerol ( 7 ) , 9-n-butyl-isoguaiacylglycerol ( 8 ) , 8' -methoxy-olivil ( 9 ). Conclusion : Compounds 5 - 9 are isolated from this plant for the first time.
