ABSTRACT:
Azadirachtin is effectively recovered from the seeds of the neem tree by crushing the seeds, extracting azadirachtin from the crushed seeds with water and then either extracting azadirachtin from the water using a non-aqueous solvent which is not miscible with water and has a higher solubility of azadirachtin than water or a surfactant having a turbidity temperature between 20.degree. and 80.degree. C. The concentrated azadirachtin is easily recovered from the second extraction solution and shows high activity as an insecticide.
