Abstract

Plants have been used for many years as a source of traditional medicine to treat various diseases and conditions. R. cristatus DC (Polygonaceae) is widely spread in Turkey and used as both herbal medicine and food. This study examined the antioxidant activities of ethanolic extract of R. cristatus DC using different tests. The antioxidant activity of ethanolic extract of R. cristatus leaves was analyzed for total phenolic, flavonoid, ascorbic acid and β-carotene contents, reducing power and DPPH radical scavenging activity. The results were compared with natural and synthetic antioxidants. The results suggest that consumption of R. cristatus DC can be beneficial effects due to its antioxidant properties

Keywords
