ABSTRACT
Extracts of seed of Garcinia kola were used to determine the antibacterial properties of the extract. Methanol and ethanol were used for the extraction. Minimum inhibitory concentration (MIC; mg/ml) and Minimum bactericidal concentrations (MBC; mg/ml) of the extract as well as zones of inhibition of the extract were determined. Seed extract of Garcinia kola was more effective in inhibiting the growth of Staphylococcus aureus at 25mg/ml concentration. The variation in the antibacterial activities is presumed to be due to different active compounds present in the extract. The aim of this research is to determine the antibacterial activity of Garcinia kola extracts on some test organisms. The findings of this research concluded that the antibacterial effect and inhibitory concentration of Garcina kola was more effective in modern day use of traditional medicine.
