Studies on the chemical constituents of the flowers of Azadirachta indica have led to the isolation of one new flavanone named as azharone (5,7,4'-trihydroxy-3'-(3''-methyl-2'',3''-epoxybutyl)flavan-4-one (3)) along with two known constituents azadirone (1), and isoazadironolide (2). Their structures have been elucidated through spectral studies including 2D-NMR (COSY-45, NOESY, J-resolved, HMQC, HMBC) experiments.
对印楝花化学成分的研究已导致分离出一种名为阿扎隆（5,7,4'-三羟基-3'-(3''-甲基-2'',3''-环氧丁基)黄烷-4-酮（3））的新黄酮酮，以及两种已知成分印楝酮（1）和异印楝诺内酯（2）。它们的结构已通过包括二维核磁共振（COSY-45、NOESY、J-分解、HMQC、HMBC）实验在内的光谱研究得以阐明。
