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.

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.
