Abstract
Abstract Nimbin, the crystalline principle of M. azadirachta Linn. is assigned the molecular formula C 29 H 36 O 9 . 1,2,5-Trimethylnaphthalene was isolated from the dehydrogenation of a reduction product of nimbin. The products of alkaline degradation and pyrolytic experiments establish that nimbin possesses either of the partial structures X or XI.
