ABSTRACT

 

Article No.: 01082003

Type: Research

 

 

The study evaluated phytochemical components of plant oil extracted from three common indigenous plants; Acalypha godseffiana, Annona muricata and Petiveria alliacea spatially distributed in South west Nigeria. Oil extraction was performed in a standard laboratory according to Association of Official Analysts and Chemist (AOAC, 2003) procedures. Results from the assay shows that A. godseffiana oil extract possesses higher phytochemical contents; tannin (7.76mg/ml), flavonoids (14.3mg/ml), cardiac glycosides (20.9mg/ml) terpenoids (11.9 mg/ml) and alkaloids (24.38%) than the oil extract from the other medicinal plants. Furthermore, oil extract from A. godseffiana reflected higher cumulative phytochemical constituents. These phytochemicals were noted to act as insecticidal agents, thus essential in the management pest agricultural pest of economic importance. Rigorous biochemical characterization of the oil extracts is suggested for identification and isolation insecticidal compounds of interest.
