text: Furthermore, the process details require greater simplification in steps (1), (2) and (3) for large scale operations such as, pre-extraction of neem seed kernels with hexane, before extraction with acetone, should also be avoided since azadirachtin is unstable at the boiling point of acetone (57°C) compared to ambient temperature.
text: The extraction methodology requires modification for manufacturing dry azadirachtin powder suitable for novel formulations, since azadirachtin is known to be unstable at high temperatures, extraction at refluxing temperature of ethanol has to be avoided.

text: The extraction methodology requires modification for manufacturing dry azadirachtin powder suitable for novel formulations, since azadirachtin is known to be unstable at high temperatures, extraction at refluxing temperature of ethanol has to be avoided Refluxing of powdered neem kernels with 95% ethanol is not convenient for large scale extractions, economically.
text: Although azadirachtin has very potent insecticidal activity, it is highly unstable in aqueous medium and extremely sensitive to sunlight.
