Preliminary Investigation on the Phytochemistry and Antimicrobial Activity of Senna alata L. Flower
M. Idu, S.E. Omonigho and C.L. Igeleke

Abstract:
Preliminary studies on the phytochemistry and extracts of water, methanol, chloroform and petroleum ether, of Senna alata flowers were examined for antimicrobial properties. Extracts tested at a final concentration of 500 μg mL-1 produced in vitro antimicrobial activities in assays against clinical isolates of Staphylococus aureus, Candida albicans, Escherichia coli, Proteus vulgaris, Pseudomonans aureginosa and Bacillus subtilis. The zones of inhibitions produced by the extracts in agar diffusion assay against the test micro organisms ranged from 4 to 10 mm while the gentamycin antibiotic control, produced zones that measured 5 mm. Preliminary phytochemical analysis of the plant extracts showed the presence of phenols, tannins, anthraquinoes, saponins, flavonoids.
