Description

The present study was conducted to evaluate the antimicrobial activity of Bougainville spectabilis stem, leaves and flowers dissolved in various solvents. Antimicrobial activity of different solvent extracts of B. spectabilis was tested against poultry strains of Salmonella gallinarum (S.gallinarum) and Escherichia coli (E.coli) by disk diffusion method. Distilled water was used as negative control, ciprofloxacin and ampicillin were used as positive control in S. gallinarum and E.coli respectively. The studies also include the qualitative analysis of various phytochemical components e.g., (Alkaloids, Flavonoids, Glycosides, Phlobatanins, Saponins, Tanins, Steroids and Terpenoids) present in the B. spectabilis extracts of stem, leaves and flowers dissolved in various solvents. By observing the inhibition zones there was no significant difference in the results obtained for the different extracts of the B. spectabilis stem, leaves and flowers. In this way we may indicate that different parts of B. spectabilis have potentials as antibacterial herbal remedies in poultry.
