Abstract
Qualitative phytochemical screening of ten locally available insecticidal plants such as Adathoda vasica (Ness) (Acanthaceae), Cynodon dactylon (Linn.) Pers. (Poaceae), Eclipta alba (Linn.) (Asteraceae), Morinda pubescens J.E.Smith (Rubiaceae), Ocimum tenuiflorum (Linn.) (Labiatae), Phyllanthus amarus (Linn.) (Euphobiaceae), Sesbania grandifolora (Linn.) (Fabaceae), Solanum surattense (Linn.) (Solanaceae), Solanum trilobatum (Linn.) (Solanaceae), and Vinca rosea (Linn.) (Apocynaceae) were investigated. Petroleum ether (40 – 600 C), hexane, chloroform, ethanol and water were used as solvents. Secondary metabolities steroids, alkaloids, phenolic compounds, flavonoids, saponnins, tannins, aromatic acids, and xanthoproteins were analysed using standard procedures. Tannins was found from water and hexane extracts of S. grandifolora and E. alba respectively. Except the chloroform extract of A. vasica, petroleum ether, ethanol extracts of O. tenuiflorum and petroleum ether and hexane extracts of V. rosea had alkaloids.
