In vitro Antioxidant Properties and Phenolic Content of Ginger (Zingiber officinale Rosc.) Root
Ginger root is one of the most widely used plants for medicinal aims in Anatolia. Determination of antioxidant properties and of phenolic contents traditionally used plants is important in respect to pharmacologic studies. In this study, antioxidant properties and phenolic content of ginger (Zingiber officinale Roscoe) root are investigated. Antioxidant activity of plant is measured with ferric thiocyanate method, reducing power and metal chelating assays. Also, antiradical activity of ginger (Zingiber officinale Roscoe) root is measured with 1,1-diphenyl-2-picryl-hydrazyl (DPPH•) radical scavenging activity. Additionally total phenolic content of plant are determined by the Folin-Ciocalteu reactive method. Butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), α-tocopherol and trolox were used as standard antioxidants for comparison. It has been show that ginger (Zingiber officinale Rosc.) root have gat antioxidant and antiradical properties and there is the correlation between these properties and phenolic and flavonoid contents of plant.
