ABSTRACT
Gum arabic (GA) is an exudate from acacia seyal and acacia senegal trees, which belong to the leguminosae family. There are many applications for GA, such as use as a food additive, shelf-life enhancement, microencapsulation, satiety induction, use as anti-obesity, antimicrobial, and anti-inflammatory agent, use as an anticoagulant, and applications in tumor imaging and nanotechnology. Little has been described about the mechanisms by which GA provides its protective effects, especially its role as an antioxidant, to different body tissues and organs. The aim of this study was to review the recent evidence of the antioxidant effects of GA on different body organs and tissues. The new PubMed system, which was recently released in October 2019, was used to collect and analyze data for this review. There were only seven articles in PubMed that described the antioxidant and protective effects of GA on different body organs and tissues in the period from January 2015 to November 2019; there be four articles from 2019. The results of these studies revealed the protective and antioxidant effects of GA on the liver, kidney and blood and cardiovascular system in experimentally induced injuries of these organs and tissues. Further studies are required to study the protective and antioxidant effects of GA on other body organs and tissues. The new PubMed system is a powerful and smart tool for searching and collecting data and for saving researchers time and effort; it is highly recommended to be widely used.
