Abstract: Phytochemicals are naturally occurring compounds present in all plant parts which together with nutrients and fibres provide protection to plants and humans against diseases. The types and the quantity of phytochemicals vary from one plant to another. This study is aimed at determining the phytochemicals and antimicrobial activities of five medicinal plants growing in Nigeria. The phytochemical analysis revealed the presence of flavonoids, saponins, tannins carbohydrate, terpenoids, glycosides and anthraquinones in the plant extracts. The antimicrobial screening was carried out using the following organisms; B. subtilis, C. species, S. aureus, S. pyogenes, E. coli, P. aeruginosa, S. typhi, S. dysenteriae and C. albicans. Chromolaena odorata leaf extract was found to contain all thesecondary metabolites under investigation with exception of anthraquinones and showed activity against all the tested organisms at 100 mg/ml. The evidence of these phytocompounds with inhibiting effect against the tested organisms could be the reasons for their uses in treatment of the various claimed diseases traditionally.
