Introduction: In different African and Middle East countries, people used to chew Garcinia kola(G.K) seeds driven mainly by beliefs of traditional backgrounds. Recently, G.K was researched for its prospected antimicrobial benefits. Aims: To study the antimicrobial effects of G.K on some standard laboratory bacteria and fungi. Objectives: To test the effect of different concentrations of water extracts and ethanol extracts of G.K. on four bacteria and two fungi; namely Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger. Materials and methods: Seeds of Garcinia cola were obtained from the local market. Samples were extracted by cold extraction technique using ethanol and water. The paper disc diffusion method was adopted with some minor modifications to assess the antibacterial activity of the prepared extracts. Results: All water and ethanol extracts of G.K, showed antimicrobial activity. Conclusion: G.K. has antimicrobial activity against the different bacteria and fungi tested. Activity was measured by the width of the inhibitory zone which varied with solvent and concentration of the active substance.
