ABSTRACT

Fagonia glutonosa (L.) (Zygophyllaceae) is a medicinal plant traditionally used as an mainly as a popular remedy for the treatment of various skin lesions and for the treatment of various other digestive diseases. Preliminary phytochemical screening of the plant showed the presence of large amounts of phenolics and flavonoids, anthraquinones, terpenes, saponins, alkaloids, coumarins and tannins. Subsequent quantification showed the presence of 0.74% (m/m) phenolics (calculated as gallic acid) and 0.13% (m/m) flavonoids calculated as catechin equivalents per 100 g of fresh mass. The presence of phenolic compounds prompted us to evaluate its antioxidant activity. In the present study, methanolic extract of aerial parts of Fagonia glutonosa was screened to evaluate its free - radical scavenging effect. The highest antioxidant and free radical scavenging ability of the extract was observed at a concentration of 2500 µg mL–1.
