The results obtained demonstrated that the aqueous extract of P. dactylifera fruit exhibited significant immunostimulatory effects on humoral immunity. It achieved this by enhancing complement activity and increasing splenocyte (including B-lymphocytes) proliferation by 142.5% compared to control cells. Similarly, in the same conditions, there was notable stimulation of cellular immunity through thymocyte activity, resulting in a remarkable increase in cell proliferation (225%) and a boost in thymocyte function (245.9%), which plays a role in safeguarding against cancer. Moreover, the date extract demonstrated anti-inflammatory properties. This was evident in the increased phagocytosis activity mediated by macrophages under the ethyl acetate extract, effectively eliminating pathogens. Assessing the cosmetic potential of date extracts showed that the ethyl acetate extract possesses both anti-inflammatory and strong antioxidant effects, exhibited high photo absorption of ultraviolet-B rays. Based on these findings, we propose to study the utilization of this extract for sun protection as a sunscreen. Furthermore, the Fourier-transform infrared spectroscopy analysis indicated that the most active compounds present were flavonoids.
