dc.description.abstract Date pits contain valuable components but are often overlooked and considered as waste. In order to valorize date pits, this study aimed to evaluate the antimicrobial activity of ethanolic extracts prepared from the pits of two varieties of Phoenix dactylifera L.: "Ghars" and "Timjouhart". The antimicrobial activity test showed that the ethanolic extracts [600mg/ml] were active against all tested microbial strains, including Staphylococcus aureus, Candida albicans, Bacillus subtilis, Escherichia coli, and Listeria monocytogenes. Particularly, they exhibited an inhibition zone diameter of 16 ± 1 mm; 14 ± 0.5 mm against Staphylococcus aureus for the Ghars and Timjouhart varieties, respectively. On the other hand, the least sensitive strains were Escherichia coli and Bacillus subtilis, with inhibition zone diameters ranging between 9 ± 0.5 mm et 10 ± 0.5 mm for both studied varieties. The presence of bioactive compounds such as flavonoids and phenolic compounds in date pits may be responsible for their observed antimicrobial activity. In conclusion, Ethanol extract, with its antimicrobial properties against various microbial strains attributed to its bioactive compounds, could be utilized for the development of new drugs or therapeutic formulations to combat infections.
