The utilization of plant materials as alternative therapies to control pathogenic bacteria has recently attracted. The effect of the fresh seed, freeze-dried seed, fresh leaf and freeze-dried leaf of using ethanol and aqueous extracts was tested on some organisms using standard laboratory procedures. The bacteria used were Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Salmonella typhi, Klebsella pneumonia and oryzae, while the fungi used were Trichoderma harzionium, Fusconium oxysporium, Aspergillus niger, Aspergillus flavus and Penicillium notatum. The results showed that the ethanol extracts of B. coriacea fresh seed showed inhibitory zones ranging from 2–12 mm, while the aqueous extract showed inhibitory zones ranging from 2-10 mm. The ethanol extracts of B. coriacea freeze dried seed showed inhibitory zones ranging from 5–38 mm, while the aqueous extract showed inhibitory zones ranging from 4-36 mm. The ethanol extracts of B. coriacea fresh leaf showed inhibitory zones ranging from 2–26 mm, while the aqueous extract showed inhibitory zones ranging from 2-24 mm. The aqueous and ethanol extracts of B. coriacea freeze dried leaf showed inhibitory zones ranging from 3-40mm respectively. The study conclude that the aqueous and ethanol extract of freeze dried seed of B. coriacea showed better antifungal and antibacterial activity against the test organisms compared with the aqueous and ethanol extract of fresh seed of B. coriacea. Similarly, the aqueous and ethanol extract of freeze dried leaf of B. coriacea showed better antifungal and antibacterial activity against the test organisms compared with the aqueous and ethanol extract of fresh leaf of B. coriacea. The ethanol extract showed better antifungal and antibacterial activity than aqueous extract.
