摘要
采用生物活性追踪法，从苦（Ｍｅｌｉａａｚｅｄａｒａｃｈ）果实中分得苦新醇（Ⅰ）、苦酮（Ⅱ）、苦醇（Ⅲ）、苦二醇（Ⅳ）、苦三醉（Ⅴ）、香草酸（Ⅵ）、香草醛（Ⅶ）和川素（Ⅷ）根据波谱（ＩＲ，ＭＳ’Ｈ－ＮＭＲ，１３Ｃ－ＮＭＲ）分析和理化常数测定确定其结构。其申Ｉ为一新化合物。生测结果表明，Ⅱ－Ⅴ和Ⅷ对菜青虫（Ｐｉｅｒｉｓ ｒａｐａｅ）有明显的拒食活性，Ⅷ还表现出明显的胃毒活性性、Ⅵ和Ⅶ仅表现出一定的拒食活性。
elianoninol, melianone, melianol, meliandiol, meliantriol, vanillic acid, vanllinand toosendanin have been isolated from the fruits of chinaberry Melia azedarach.Meiianoninol is a newly discovered compound. Their biological acivities toward thecabbage worm Pieris rapae were studied. It was found that the triterpenes melianone, melianol, meliandiol, meliantriol and toosendanin possessed strong antifeedantactivities against the cabbage worm and only toosendanin showed considerable stomach toxicity to the test insect. The bio-activities of melianoninol, vanillic acid andvanillin were much lower than the other compounds.
