Azadirachtin is a chemical compound belonging to the limonoids. It is a secondary metabolite present in the Neem tree seeds. The molecular formula is C35H44O16. Azadirachtin is a highly oxidised tetranortriterpenoid which boasts a plethora of oxygen functionality, comprising an enol ether, acetal, hemiacetal, and tetra-substituted oxirane as well as a variety of carboxylic esters. It is classified among the plant secondary metabolites.
This compound is found in the seeds (0.2 to 0.8 percent by weight) of the Neem tree, Azadirachta indica (hence the prefix aza does not imply an aza compound, but refers to the Latin species name). Many more compounds, related to Azadirachtin, are present in the seeds as well as in the leaves and the bark of the Neem tree which also show strong biological activities among various pest insects Senthil-Nathan, S., Kalaivani, K., Murugan, K., Chung, P.G., 2005 Effects of neem limonoids on malarial vector Anopheles stephensi Liston (Diptera: Culicidae). Effects of these preparations on beneficial arthropods are generally considered to be minimal. Some laboratory and field studies have found neem extracts to be compatible with biological control.
