Evaluation of inhibitory effect of Phoenix dactylifera Ethanol Seeds Extract against Escherichia coli and Staphylococcus aureus

Abstract

This study evaluates inhibitory effect of Phoenix dactylifera against Escherichia coli and Staphylococcus aureus. Extraction phytochemical screening and agar diffusion methods were employed to evaluate phytochemical profile, and antibacterial activity of Phoenix dactylifera. Alkaloids, cardiac glycosides and sapponnins are contained in Phoenix dactylifera seeds. Phoenix dactylifera seeds have promising activity against E. coli with zone of inhibition of 20.4mm. The MIC and MBC of Phoenix dactylifera seed extract are 1000μg/ml and 100μg/ml against E. coli and S. aureus respectively. Phoenix dactylifera seed could be very useful in the management of gastrointestinal infections due to E. coli.
