Phytochemical Analysis and In-vitro Antimicrobial Activity of Methanolic Leaves, Root and Stem Extracts of Bryophyllum pinnatum, Cochlospermum tintorium and Erythrina senegalensis

Aim: This Study was design to determine the phytochemical and antimicrobial activities of leaves, roots stem bark Cochlospermum tentorium, Bryophyllum pinnatum, Erythrina senegalensis obtained in Takum Town Taraba state.
 Methods: The were obtained, dried, ground, extracted using methanol. activity extract at various concentration tested agar well diffusion techniques against three human pathogens by measuring zones inhibition after incubation 24 hours
 Results: Phytochemical screening revealed presence alkaloids, glycoside, flavonoids, phenols, saponins, tannins steroids. Flavonoids however absent leaf tintorium, senegalensis. Phenol pinnatum. quantitative shows that tintorium had highest amount glycoside (1.55mg/dl) while least (0.81mg/dl). Stem pinnatum showed (7.51mg/dl) (3.54mg/dl). flavonoid (6.54mg/dl) (3.66mg/dl). recorded phenol (4.37mg/dl) (1.48mg/dl). alkaloid (1.30mg/dl) (0.72mg/dl). saponins (2.85mg/dl) (1.57mg/dg). methanolic leaf, root tentorium potent antibacterial activity, minimal Escherichia coli, Klepsiella pneumonae staphylococcus aureus.
 Conclusion: result indicates confirming folklore claim. Thus, making a strong case for isolation novel agent from this plant.
