【 摘 要 】

The crude methanol, acetone and water extracts of leaves and pits of three varieties ofPhoenix dactyliferawere tested for antibacterial action against selected Gram positive and Gram negative pathogenic bacteria. BarringEnterococcus faecalis, the acetone and methanol extracts showed good antibacterial activity againstBacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Shigella flexeneri, Staphylococcus aureus,andStreptococcus pyogenes,whereas the water extract had very little effect on all test bacterial species and there was almost negligible effect onP. aeruginosa. Pits extracts of all three varieties ofP. dactyliferawere found to be more effective than leaves extracts. Results clearly showed thatS.pyogeneswas most sensitive pathogen to the crude extracts and had shown maximum zone of inhibition. Minimum inhibitory concentration (MIC)forS.pyogeneswas found to be 1.3, 1.1, 1.6 and 1.4 mg/ml for methanol leaves and pits extracts and acetone leaves and pits extracts, respectively.
