Phenolic content, antioxidant potentials of Saponaria prostrata endemic plant

Abstract

Saponaria prostrata (S. prostrata) is an endemic and medicinal plant that contains secondary metabolites such as flavonoids, phenolic compounds, fatty acids, and triterpenoids. This study was carried out to evaluate the antioxidant potentials, and phenolic composition of S. prostrata. Antioxidant properties of the ethanol and water extracts of S. prostrata were evaluated by three different in vitro bioanalytical methods including CUPRAC and FRAP reducing antioxidant methods and DPPH radical scavenging antioxidant method. Effective antioxidant potentials of the plant extracts were found especially in the CUPRAC method. Rutin (36.3 µg/g extract) and hesperidin (32.7 µg/g extract) were characterized as major phenolic compounds of S. prostrata using an advanced HPLC technique.
