GC-MS Charaterization of Phytochemicals and Anti Microbial Properties of Chromolaena odorata Leaf Harvested from South Eastern Nigeria

The analysis of the leaf extract of Chromolaena odorata was carried out to characterize its components, GC-MS analysis was carried out in our laboratory. The spectrum obtained showed 15 peaks which translates to 15 compounds, with their molecular weight, formula and structures. Initial phytochemical screening showed the presence of alkaloid, saponins, tannins, flavonoids and triterpenoids, cardic glycosides and phenols while antraquinone glycosides was absent. Antimicrobial analysis revealed that the extract showed marked activities against Streptococcus sp, Staphylococcus sp, Pseudomonas aeruginosa but was resistant to Serratia marcescens.
