Medicinal plants constitute an effective source of both traditional and modern medicines. The emergence of drug resistant bacteria mandates the need for newer antibiotics.
ObjectiveTo evaluate the antibiotic effect of Hibiscus sabdariffa Methods Three medicinal plants have been selected for investigation of their antibacterial activities; Hibiscus sabdariffa. (Dried calyces), cacia seyal var. seyal (fresh stem bark) and Sphaeranthus suaveolens var suaveolens (herbs) The extracts of these plants at concentration of 100mg/ml have been tested against seven strains of bacteria.; qualitative tests using the Agar Well Diffusion Method have been carried out. Results E coli showed higher resistance to the plant extracts whereas Pseudomonas aeruginosa is more sensitive.
ConclusionHibiscus sabdariffa extracts showed extensive inhibition zone and were, therefore, effective as antibacterial ingredient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
