摘要
从苦楝(Melia azedarach L.)果中分得苦楝新醇(Ⅰ),苦楝醇(Ⅱ)、苦楝酮(Ⅲ)、苦楝二醇(Ⅳ)、香草醛(Ⅴ)和香草酸(Ⅵ)。根据波谱(IR,MS,~1HNMR,^(13)CNMR)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活性。
Melianoninol (Ⅰ), melianol (Ⅱ), melianone (Ⅲ), meliandiol (Ⅳ),vanillin (Ⅴ)and vanillic acid (Ⅵ)were isolated from the fruits of Melia azedarach L ..The structure of melianoninol, a new compound, was elucidated by IR ,MS,~1H NMR,^(13)CNMR and other spectral evidences. The new compound possesses some antifeeding properties against the imported cabbage worm (Pieris rarae L. ).
