Antioxidant Properties of Selected Wild Plants

The antioxidant properties of 4 Jordanian plant extracts were studied by chemical assays of total antioxidant capacity and ferric reducing power. The extracts total phenols and flavonoids contents were also determined. The plant methanolic extracts were found to have different levels of antioxidant activities in the assays tested. Considering the overall antioxidant activities, the studied plants were arranged in the following decreasing order of their antioxidant strength, Pictacia palaestina greater than Hypericum triquetrifolium greater than Arbutus andrachne greater than Ceratonia siliqua. The antioxidant activities of studied plants were explained by their content of total phenols& flavonoids.
