This study describes the qualitative phytochemical screening, antimicrobial and GC-MS analyses of the crude methanol extract of the stem and roots parts of Bidens pilosa partitioned between methanol, dichloromethane, ethyl acetate and hexane solvents. Phytochemical analysis indicated the presence of cardiac glycosides, terpenoids, flavonoids and alkaloids. Saponins were not found in any of the fractions of stem and root of B. pilosa. Antibacterial studies indicated that the lowest concentration (6.25 mg/mL) was achieved for Candida subtilis for the ethyl acetate fraction of the stem extract and hexane fraction of the root extract. Antimycobacterial test activity of these solvent fractions revealed that the hexane fraction of the root extract was susceptible to the bacterium isolate. Gas chromatography-Mass spectrometric study revealed the presence of the following compounds-cis-9-Hexadecenal, 2-hydroxyl ethyl (Z)-9-Octadecenoate, Octadecanal, Oleic acid, 4-(dimethylamino)-Benzaldehyde, 4,6,7-Trimethoxy-2,3-dihydrofuro(2,3-b)quinolone
