目的研究中国传统民族植物药米仔兰(又称树兰)Aglaia odorata Lour.枝条中杀虫活性成分.方法以生物测定为指导,采用硅胶柱、Sephadex LH-20柱以及制备薄层分离板对其成分进行分离和纯化,并通过物化性质和光谱分析对其结构鉴定.结果从中分离得到7个化合物,分别鉴定为rocaglamide(Ⅰ)、desmethyl rocaglamide(Ⅱ)、8-methoxymarikarin(Ⅲ)、7-羟基-6-甲氧基-香豆素(Ⅳ)、3′-hydroxy-methylrocaglate(Ⅴ)、3′-hydroxyrocaglamide(Ⅵ)、marikarin(Ⅶ).结论化合物Ⅳ为首次从Aglaia Lour.属植物中分离得到,化合物Ⅲ和Ⅶ为首次从米仔兰植物中分离得到.
目的研究中國傳統民族植物藥米仔蘭(又稱樹蘭)Aglaia odorata Lour.枝條中殺蟲活性成分.方法以生物測定為指導,採用硅膠柱、Sephadex LH-20柱以及製備薄層分離闆對其成分進行分離和純化,併通過物化性質和光譜分析對其結構鑒定.結果從中分離得到7箇化閤物,分彆鑒定為rocaglamide(Ⅰ)、desmethyl rocaglamide(Ⅱ)、8-methoxymarikarin(Ⅲ)、7-羥基-6-甲氧基-香豆素(Ⅳ)、3′-hydroxy-methylrocaglate(Ⅴ)、3′-hydroxyrocaglamide(Ⅵ)、marikarin(Ⅶ).結論化閤物Ⅳ為首次從Aglaia Lour.屬植物中分離得到,化閤物Ⅲ和Ⅶ為首次從米仔蘭植物中分離得到.

Object To study the insecticidal activity constituents from the twigs of traditional Chinese folk medicine "Mizilan" or "Shu-Lan" (Aglaia odorata Lour. ). Methods Seperation and purification under bioassay-directed were performed on silica gel CC, Sephadex LH-20 CC and preparative TLC. Their structures were established on the basis of physicochemical and spectral analysis. Results Seven compounds were isolated and identified as rocaglamide ( Ⅰ ), desmethyl rocaglamide ( Ⅱ ), 8-methoxymarikarin (Ⅲ), 7-hydroxy-6-methoxy-coumarin (Ⅳ), 3′-hydroxy-methylrocaglate (Ⅴ), 3′-hydroxyrocaglamide (Ⅵ), marikarin (Ⅶ), respectively. Conclusion Compound Ⅳ is isolated from the plant of Aglaia Lour. for the first time and compounds Ⅲ and Ⅶ are isolated from A. odorata for the first time.
