【摘要】 目的研究小果香椿树皮的化学成分。方法采用乙醇提取,提取物经萃取后以硅胶或凝胶等色谱法进行分离纯化,采用波谱法进行结构鉴定。结果从小果香椿乙醇提取物的乙酸乙酯部分共分离得到9个化合物,其结构鉴定为:piscidinolA(1),rel-(2α,3β)-7-O-methylcedrusin(2),trans-白藜芦醇(3),东莨菪内酯(4),槲皮素(5),(+)-儿茶素(6),10-廿九醇(7),β-谷甾醇(8)和胡萝卜苷(9)。结论化合物1～9均为首次从该植物中分离得到。更多还原

【Abstract】 Objective To study the chemical constituents from the bark of Toona microcarpa.Methods The plant material was extracted with ethanol and the extract were separated by silica gel and sephadex LH-20 column chromatography.The structures were elucidated by means of spectroscopic methods.Results Nine compounds were obtained and were established as piscidinol A(1),rel-(2α,3β)-7-O-methylcedrusin(2),trans-resveratrol(3),scopoletin(4),quercetin(5),(+)-catechin(6),10-nonacosanol(7),β-sitosterol(8)and daucosterine(9).Conclusion Compounds 1~9 are isolated from T.microcarpa for the first time.更多还原
