LARVICIDAL POTENTIAL OF EXTRACTS OF Persea Americana SEED AND Chromolaena odorata LEAF AGAINST Aedes vittatus MOSQUITO
ABSTRACT The larvicidal activity of various solvent (ethanol, ethyl acetate and n-hexane) extracts of Persea americana seed and Chromolaena odorata leaves against Aedes vittatus mosquitowas analysed. The most potent solvent (n-hexane) extracts of both plants were fractionated using column chromatography and most effective fractions isolated and identified using Gas Chromatography Mass Spectrometry and Fourier Transform Infrared techniques. Phytochemical screening revealed the presence of steroids, cardiac glycosides and terpenoids in all the extracts. The larvicidal bioassay ...
