Background This study investigates the biological activities of Anthyllis henoniana flowers extracts. Materials and Methods Antioxidant activity and the in vitro inhibitory effect of key digesting enzymes related to postprandial hyperglycemia were determined. Diabetic rats were orally and daily given the best extract from flowers of Anthyllis henoniana at a dose of acarbose for one month. Results Among the extracts, the ethyl acetate one displayed remarkable antioxidant activity including DPPH (IC50 = 2.34 mg/mL) and was more effective in inhibiting α-glucosidase (IC50 = 17 μg/mL) than α-amylase (IC50 = 920 μg /mL) activities. In vivo, the results proved that ethyl acetate extract at doses of 400 mg/kg bw decreased significantly the blood glucose level and lipid profile levels and increased the activities of antioxidant enzymes. These protective impacts of Anthyllis henoniana ethyl acetate flowers extract were confirmed by histological results. Conclusion This study demonstrates, for the first time, that Anthyllis henoniana flowers ethyl acetate extract is effective in inhibiting hyperglycemia and oxidative stress caused by diabetes.

The aim of this study was to evaluate the antioxidant, the anti-inflammatory, and the antitumoral activities of the aqueous ethanolic extract from Phoenix dactylifera L. 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 IC50 value 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 A2 activity as well as on carrageenan-induced paw oedema in mice. The in vitro study showed that the extract inhibited the phospholipase A2 activity with an IC50 value of 130 μg/mL and the in vivo study 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 IC50 values of 8 and 18 mg/mL, respectively, after 72 h treatment. These results confirm the ethnopharmacological significance of Phoenix dactylifera L. parthenocarpic dates, which could add support for its pharmaceutical use.
