Identification of Insecticidal compounds in Saraca asoca Bark Extract Using Gas Chromatography and Mass Spectroscopic Technique

S. Gomathi and K.M. Subbu Rathinam* ABSTRACT To identify the insecticidal components of Saraca asoca bark were evaluated by standard protocol using the equipment Perkin-Elmer Gas Chromatography–Mass Spectrometry. 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 1-Butyl (dimethyl) silyloxypropane, 1,2,3-Benzenetriol, Squalene, Phenol, 3,4,5-trimethoxy, Hexadecanoic acid, methyl ester, Hexadecanoic acid, methyl ester, Stigmast-5-en-3-OL, (3.Beta.) and 7-Methoxy-2,3,6Triazaphenothiazin-1(2H)-one in the ethanolic extract of Saraca asoca. Among the various compounds, 1,2,3-Benzenetriol, Squalene, phenol and 7-Methoxy-2,3,6Triazaphenothiazin-1(2H)-one identified as insecticidal activity using NIST library. These findings support the use of Saraca asoca as insecticidal plant.
