Phytochemical profile and antioxidant activity potential of Lotus sanguineus (Vural) D.D.Sokoloff

The in vitro antioxidant activity and phenol, phenolic acid, flavonoid, and proanthocyanidin content of Lotus sanguineus (Vural) D.D.Sokolof extracts were investigated. The aerial parts of Lotus sanguineus have high antioxidant activity. While the ethyl acetate extract has the highest antioxidant activity, in contrast the hexane extract shows lowest activity. In addition, phytochemi-cal antioxidant compounds, phenolic substance, phenolic acid, flavonoid and proanthocyanidin contents of the extracts were determined. The highest total phenolic, phenolic acid, flavonoid and proanthocyanidin contents were found in the ethyl acetate extract. The obtained data supported the result that the plant has antioxidant activity.
