Mangopeel powder supplementation prevents oxidative stress, inflammation, and fibrosis in carbon tetrachloride induced hepatic dysfunction in rats

Abstract

The study reports the phenolic profiles and hepatoprotective properties of mango peel powder against carbon tetrachloride (CCl4) induced hepatic damage in rats. It was found that the mango peel possesses high amount of polyphenols and flavonoids as analyzed by HPLC-DAD. Supplementation of mango peel powder in CCl4 administered rats exhibit strong protective effects in vivo. The results suggest that mango peel powder supplementation antagonized the CCl4-induced increase in serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase activities and hepatic malondialdehyde levels. Furthermore, mango peel powder supplementation prevented decrease in antioxidant catalase activity and glutathione concentration in CCl4-administered rats. Mango peel powder supplementation also prevented the inflammatory cells infiltration and fibrosis in liver of CCl4 treated rats. This finding demonstrates that the polyphenol-rich mango peel powder can be explored as a chemopreventive or chemotherapeutic agent against oxidative-stress-related liver disorders. Practical applications Mango (Mangifera indica L.), the most important fruit in Anacardiaceae family, is a tropical fruit which possesses high nutritional and medicinal value. The research showed that mango peel possesses numerous phenolic antioxidants. The results also demonstrated that mango peel powder exerts a protective effect against carbon tetrachloride-induced liver injury in rats. Every year, considerable amount of mango peel is produced in juice industries which are left as waste product. Thus, this project will provide a potential source of phenolic compounds and potential approach to prevent liver diseases.
