 Title    Isolation and Characterization of l-Tigloyl-3-acetylazadirachtol from the Seed Kernels of the Thai Neem Azadirachta siamensis Valeton  
 Abstract    The Thai neem A. siamensis (Valeton) is the main source for botanical insecticides in Thailand. Although azadirachtin A (aza A) is present in Thai neem, there are som e other related compounds which may contribute to its bioefficiency. Analytical HPLC of Thai neem samples showed a peak closely eluted with azadirachtin. A large-scale cleanup involving two liquid/liquid extraction steps, silica filtration, and finally two successive preparative HPLC separations, resulted in the pure compound, which was identified as l-tigloyl-3-acetylazadi-rachtol by ID -and 2D -'H and 13C NM R spectroscopy.
