STUDIES ON THE CHEMICAL CONSTITUENTS OF MELIA AZEDARACH L.
-
Abstract
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,13CNMR and other spectral evidences. The new compound possesses some antifeeding properties against the imported cabbage worm (Pieris rarae L. ).
