Antioxidant, Anti-Inflammatory, and Antitumoral Effects of Aqueous Ethanolic Extract fromPhoenix dactyliferaL. Parthenocarpic Dates
The aim of this study was to evaluate the antioxidant, the anti-inflammatory, and the antitumoral activities of the aqueous ethanolic extract fromPhoenix dactyliferaL. parthenocarpic dates. The antioxidant activity was carried using DPPH radical scavenging activity. The result showed that parthenocarpic dates had strongly scavenging activity on DPPH reaching 94% with an IC50value of 0.15 ± 0.011 mg/mL (p < 0.05). The anti-inflammatory potential was determined by the inhibitory effect of the aqueous ethanolic extract on phospholipase A2activity as well as on carrageenan-induced paw oedema in mice. Thein vitrostudy showed that the extract inhibited the phospholipase A2activity with an IC50value of 130 μg/mL and thein vivostudy showed a significantly decrease in the paw oedema after 1 h compared to the control group. Finally, the antiproliferative activity of the aqueous ethanolic extract was assessed by MTT test against MCF-7 and MDA-MB-231 cancer cell lines. This extract was effective in inhibiting MDA-MB-231 and MCF-7 cancer cells growth with IC50values of 8 and 18 mg/mL, respectively, after 72 h treatment. These results confirm the ethnopharmacological significance ofPhoenix dactyliferaL. parthenocarpic dates, which could add support for its pharmaceutical use.
