Abstract :

In the present study leaf and bark of Cleistanthus collinus were extracted with various solvents using cold percolation method. Methanol was found to be the best extractant amongst all the solvents. The crude methanol extract and solvent extract were then subjected to prescreen assays to check any insecticidal activity. Both leaf and bark extract showed some insecticidal activity against insects Plutella xylostella, Helicoverpa armigera, Spodoptera litura. Leaf extract showed more insecticidal activity (20–30%) compare to bark extract. When leaf and bark extract were partially purified using solvent extraction procedure, chloroform fraction of both leaf and bark extracts was found to have insecticidal activity against Plutella xylostella (40%). The present study has exploited the probability of having any insecticidal molecules present in the medicinally important plant Cleistanthus collinus.
