Abstract

Introduction: Medicinal plants constitute an effective source of both traditional and modern medicines. The emergence of drug resistant bacteria mandates the need for newer antibiotics.
Objective: To evaluate the antibiotic effect of Hibiscus sabdariffa.
Methods: Three medicinal plants have been selected for investigation of their antibacterial activities; Hibiscus sabdariffa. (Dried calyces), acacia 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.
Conclusion: Hibiscus sabdariffa extracts showed extensive inhibition zone and were, therefore, effective as antibacterial ingredient.
