The Antioxidant Activities and Total Phenol Contents of Eleven Turkish Medicinal Plants

Abstract

In this study, we assessed antioxidative activities and total phenol contents of Achillea biebersteinii, A. setacea, Anthemis pseudocotula, A. tinctoria var. tinctoria, Artemisia austriaca, Cistus laurifolius, Nepeta italica, Paliurus spina-christi, Primula vulgaris, Rubus sanctus, and Salvia verticillata used as folk medicine in Anatolia. The antioxidant activities of decoctions or infusions prepared from plants were evaluated by in vitro models including, ABTS radical scavenging assay, metal chelating assay, and ferric reducing power. Except for A. tinctoria var. tinctoria infusion in reducing power capacity assay and P. spina-christi decoction in metal chelating activity, all extracts displayed high antioxidant activity in all three antioxidant assays. In particular, C. laurifolius infusion showed a potent antioxidant effect as well as all references used to evaluate activity. The phenol contents of the extracts were in the range 262.70 ± 2.06-48.10 ± 0.68 mg gallic acid equivalent/g extract. The findings justify folkloric use of these plants used in the treatment of diseases such as colds, cough, colds, tonsillitis and bronchitis.
