Phenolic composition and antioxidant properties of Eryngium maritimum (sea holly)
Journal Title: Journal of Coastal Life Medicine - Year 2017, Vol 5, Issue 5
Abstract
Objective: To examine the antioxidant potential of Tunisian Eryngium maritimum (E. maritimum) leaf, root and stems extracts, as well as their phenolic compositions. Methods: The antioxidant activity of different extracts was assessed using DPPH free radical and hydrogen peroxide scavenging assays. Phenolic profiles were determined by means of liquid chromatography (HPLC-DAD). Results: All plant parts were a rich source of phenolics. Polyphenols and flavonoids were present in leaf extracts. E. maritimum leaf extracts displayed the strongest H2O2 scavenging activity (IC50 = 76.83 µg/mL) and the highest DPPH scavenging activity value (IC50 = 47.87 µg/mL) compared to other extracts. Good relationships were observed between antioxidant activities and the total phenolic and flavonoid contents. Nine bioactive compounds were detected in E. maritimum extracts. Conclusions: Our results provided evidence that E. maritimum could be an interesting source of natural antioxidant that can be used to treat divers diseases.
