ABSTRACT
This study was carried out to investigate the nutritional value and the antibacterial activity of bitter kola, (Garcinia kola). The result of the proximate analysis shows that bitter kola contains 51.95% moisture, 5.55% Ash, 9.75% crude fibers, 4.65% crude fat, 7.35% crude protein and 20.85% carbohydrate. The anti-bacterial activity shows that bitter kola can inhibit the E. coli and Staphylococcus aureus with diameter zone of inhibition of 14mm and 16mm respectively. There was no inhibition against Salmonella species tested for. The result of this research shows that bitter kola, can be eaten as food, as well as serve a purpose in the production of drugs which can be used to treat infections caused by E. coli and Staphylococcus aureus.
