To identify the insecticidal components of Ficus benghalensis bark were evaluated by standard protocol using the equipment Perkin-Elmer Gas Chromatography–Mass Spectrometry (GCMS). The mass spectrum of the compounds found in the extract was matched with the National Institute of Standards and Technology (NIST) library. The GC-MS analysis revealed the presence of various compounds like 9, 12, 15-Octadecatrienoic acid, methyl ester, 9-Octadecenoic acid, 2-Hexadecen-1-ol, 3, 7, 11, 15-tetramethyl-, [R-[R*, R*-(E)] and 9, 12-Octadecadienoic acid identified as insecticidal activity using NIST library. These findings support the use of Ficus benghalensis bark extract as insecticidal plant.
