Freshmaterial of the palm heart was dried, crushed and then extracted with distilled water, methanol and acetone.Distilled water extract was divided into crude, residues (after filtration), protein and non-protein parts. All extractswere investigated to determine their inhibitory activity against Staphylococcus aureus (S. aureus), Streptococcuspyogenes (S. pyogenes), Streptococcus mutans (S. mutans), Escherichia coli (E. coli), Klebsiella pneumoniae (K.pneumoniae), Proteus mirabilis (P. mirabilis), Enterobacter aerogenes (E. aerogenes), Morganella morganii (M.morganii), and Pseudomonas aeruginosa (P. aeruginosa) using agar well diffusion method, ceftriaxone (CTR) wasused as a positive control. Phytochemical analyses were also performed to confirm the presence/absence ofbioactive constituents. All extracts revealed antibacterial activity against some of the tested bacteria. Whencomparing the findings, aqueous (watery) extracts had the slightest antibacterial activity while the highest activitywas related to acetone extraction. For Gram-positive bacteria, the highest activity of acetone extract was against S.mutans (10.7±0.13 mm) followed by S. pyogenes (10.6±0.17 mm), while Gram-negative most sensitive strain wereE. aerogenes (15.3±0.20 mm) and P. mirabilis (14.4±0.48 mm) respectively. Phytochemical analyses haverevealed the presence of steroids, alkaloids, pseudotannins, glycosides, carbohydrates, and aromatic amino acids.Finally, these findings indicate the activity of the heart of palm to fight germs, further studies may also be needed
