                            The present invention relates to an insecticidal enriched extract (biopesticide) isolated from the stem of Nothapodites foetida (Wight) Sleumer (formerly Mappiafoetida (Miers) useful for the insect free storage and transport of grains and seed. The insecticidal activity of the enriched extract (biopesticide) of the invention is ascribed to compound/s other than camptothecin. The invention further relates to the process for preparation thereof, containing Compounds of general formula 1 and formula 2 (General formula 1) wherein R1=CH 3, CH2OAC and wherein R2= COOH, or (I) and R3=H. OH. (Formula 2)
