Azadirachta indica, commonly known as neem, margosa, nimtree or Indian lilac, [3] is a tree in the mahogany family Meliaceae. It is one of the two species in the genus Azadirachta . It is native to the Indian subcontinent and to parts of Southeast Asia , but is naturalized and grown around the world in tropical and subtropical areas.
The genus Azadirachta was established by Adrien-Henri de Jussieu in 1830. [1] In 1753, Carl Linnaeus had described two species, Melia azedarach and Melia azadirachta. [3] De Jussieu considered Melia azadirachta to be sufficiently different from Melia azedarach to be placed in a new genus, Azadirachta, as Azadirachta indica. [4]
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 scientific species name).
Meliaceae, the mahogany family, is a flowering plant family of mostly trees and shrubs (and a few herbaceous plants, mangroves) in the order Sapindales.. They are characterised by alternate, usually pinnate leaves without stipules, and by syncarpous, [2] apparently bisexual (but actually mostly cryptically unisexual) flowers borne in panicles, cymes, spikes or clusters.
