摘要：

Azadirachtin-A when exposed to UV light (254 nm), as a solid thin film on a glass surface, furnished only a single photoproduct, The photoproduct was isolated by repeated column chromatography and identified by NMR and mass spectroscopy. NMR data indicated that the (E)-2-methylbut-2-enoate ester group of azadirachtin-A has been converted into (Z)-2-methylbut-2-enoate ester, Half-life of azadirachtin-a as thin film under UV light was found to be 48 min.
