摘要
从苦楝(Melia azedarach L)果中分得苦楝新醇(melianoninol,I)、苦楝醇(melianol,II)、苦楝酮(melianone,III)、苦楝二醇(meliandiol,IV)、香草醛(vanillin,V)和香草酸(vanillicacid,VI)。根据波谱(IR.MS,~1HNMR,~13CNMR)分析和理化常数测定,确定了它们的结构。其中苦楝新醇(I)为新化合物,对菜青小虫有一定的拒食作用。
A new compound named melianoninol(I),along with five known corn- pounds melianol(Ⅱ),melianone(Ⅲ).meliandiol(Ⅳ),vanillin(Ⅴ)and vanillic acid(Ⅵ)was isolated from the fruits of Melia azedarach L..Their structures were elucidated by IR. MS,~1HNMR,^(13)CNMR,and other spectral evidence.Compounds Ⅱ,Ⅲ,Ⅳ possess different insecticidal effects.and Ⅰ exhibits a certain antifeeding property against the cabbage worm. (Pieris rapae L.).
