This study investigated the invitroantibacterial activities of ethanol seed extractof RicinodendronheudelotiiagainstStaphylococcusaureus, Escherichiacoli and Bacilluscereus. The extracts were tested against the bacteria using the disc diffusion method at various concentrations of400mg/kg, 800mg/kg, 1200mg/kg, 1600mg/kg and the undiluted.Dataobtained showed resistance of Staphylococcus aureus and Bacillus cereus to all concentrations of the seed extract except at undiluted concentration with inhibition zones at 10mm and 14mm respectively.Escherichia coli was inhibited by the seed extract at 16mm each for 400mg/kg, 800mg/kg and the undiluted concentration at 13mm. Staphylococcusaureus, Escherichiacoli and Bacilluscereusshowed no significant inhibition at lower concentration of the extract while the undiluted extract showed inhibition against the three organisms used at 10mm, 13mm and 14mm respectively. It can be concluded that the ethanol seed extract ofRicinodendronheudelotiican be used as a potential antimicrobial therapy at undiluted concentration against Staphylococcusaureus, Escherichiacoli and Bacilluscereus.
