The correlation between the AOA (antioxidant activity) and the TPC, TTC, TFC was with r2 = 0.999). The two major compounds identified and quantified by LC/MS are quercetin and ellagic acid, with a respective retention time of 15.42 min for ellagic acid (2.5 ± 0.3 µg/ml) and 26.90 min for quercetin (6.8 ± 0.2 µg/ml). The different extracts showed an average activity of trapping two free radicals of the order of IC50: 15.6 ± 0.012 μg/ml, equivalent to a %IP of 84.46 ± 1.78. The values of TPC, TFC and TTC were 34.6 ± 0.02 mg GAE/ml, 56.6 ± 0.4 mg CE/ml and 34.78 ± 0.03 mg CE/ml, respectively. ![]() Total polyphenol content (TPC), total flavonoid content (TFC) and total tannin content (TTC) were evaluated using a UV spectrophotometer. The antioxidant activity was evaluated by the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. This study evaluates the content of total phenols, the antioxidant activity of the extracts of the leaves of this plant. Despite the biological and therapeutic virtues of this plant, no information on the content of total phenols and on the antioxidant activity exists.
