Background: Medicinal plants are used to treat various ailments in
Kenya. This study describes the antibacterial activity of medicinal
plant extracts used in traditional medicine in Kenya. Seven medicinal
plants were studied to determine antimicrobial effect of plant extracts
in vitro after phytochemical screening.
Materials and methods: Dry materials of the plants, A. remota, B.
micrantha, S. didymobotrya, C. africana, P. peruviana, P. africana,
and A. annua were sequentially extracted using three solvents - water,
methanol, and hexane. Antimicrobial activity of plant extracts
against E. coli, P. aeruginosa, B. cereus and M. smegmatis was determined
by Kirby Bauer disc diffusion assay.
