The GC/MS/MS analysis of extracts of an endophytic fungus of entomopathogenic nature, Phomopsis sp. culture filtrate gave us eleven major compounds. All compounds identified by GC/MS/MS screening were assessed for their insecticidal property using physico-chemical property calculations according to Tice Rules. The presence of Dodecanoic acid ethylester, and Phthalic acid, octyl 2-pentyl ester reveled that the extract of Phomopsis sp. might have insecticidal activity. A compund namely, 1-2’desoxy-3’5’octetraisopropyldisiloxane, 3diyl3-beta riborotroxy (C21H43N5O4Si2) is recorded as a major compound with 77.75% which is not reported earlier might have shown promise to use as a source of novel insecticide.
