Dietary Gum Arabic Supplementation Alter Plasma and Tissue Antioxidant and Free Radical Scavenging Activities in Sprague Dawley Male Rats

Abstract

The aim of this study was to determine the antioxidant activities of dietary Gum Arabic supplemented in male rat model. In this study, the Sprague Dawley rats were separated into two groups as follows: the normal control group (NC) and Gum Arabic group (GA). At the end of eight weeks of treatment, the Ferric Reducing Antioxidant Power (FRAP) , 1, 1- Diphenyl-2-picryl-hydrazyl (DPPH) levels, and the total phenol content of the GA extracts, plasma and liver tissue were evaluated. The results showed an increased of plasma and liver antioxidant activates in the GA groups as compared to the NC group. Administration of dietary GA reduced the FRAP and TPC concentration in the plasma and in the liver the GA group. Based on these results, it can be concluded that GA supplemented is the natural antioxidants, especially phenolic compounds, which may act both by reducing the content of toxic compounds in foods and by supplying the human body with exogenous antioxidant.
