the principle active constituent of Azadirachta indica ranges from 0.3
to 0.6 per cent. A simplified procedure, when compared to established methods, has
been adopted to enrich azadirachtin ‘A’ to 50 per cent using minimum possible steps
without resorting to chromatographic techniques. It involves additional partition
with CCl4 before
final extraction which removes most of nimbin, salanin, and allied triterpenoids.
Enriched product finds immense utility in preparing formulations with high azadirachtin
and also in isolating pure azadirachtin by adopting preparative HPLC
