Abstract :Rosa canina L. is a climbing wild rose plant species native to Europe, Northwest Africa, and Western Asia from the Rosaceae family. Antioxidants such as polyphenols and ascorbic acids, as well as carotenoids, Vitamin B and E, are abundant in the flesh of Rosa canina fruits. Plant phenolics, particularly flavonoids, have attracted a lot of attention in recent years because of their wide range of biological effects, including antiinflammatory, antiallergic, and antibacterial properties. Functions of flavonoids as antioxidants, free radical scavengers, and divalent cation chelators were recorded in the literature among others. Epidemiologic studies have shown a link between increased flavonoid antioxidant intake and a lower risk of cardiovascular disease and certain types of cancer. In this experiment, dry and fresh fruits of Rosa canina from two regions insert ignore into journalissuearticles values(Turkey and Iran); were investigated according to in-vitro antiradical assays such as insert ignore into journalissuearticles values(2,2′-diphenyl-1-picrylhydrazyl radical insert ignore into journalissuearticles values(DPPH●); scavenging activity and 2,2`-azino-bisinsert ignore into journalissuearticles values(3-ethylbenzothiazoline-6-sulfonic acid insert ignore into journalissuearticles values(ABTS+●);. The phenolic composition of the extracts was also analyzed by HPLC and spectrophotometric methods.
