Aims: Ethyl acetate fraction of total phenols from Zanthoxylum zanthoxyloides leaves was evaluated for its effects in alloxan-induced diabetic male albino rats.
Methodology: Diabetes was induced in rats by administrating alloxan monohydrate at a dose of 130 mg/kg body weight. The ethyl acetate fraction was administered to rats at 100, 200 and 400 mg/kg b.w. daily for 15 days. Blood glucose, lipid profile and pancreatic histopathology were monitored using standard methods.
Results: Results indicated that two weeks after treatment with Z. zanthoxyloides, significant (p<0.05) reductions in hyperglycemic blood glucose, total cholesterol and low-density lipoproteins (LDL) were recorded; with lowest values recorded in the group treated with the highest concentration of the extract. Histopathological examination of pancreatic tissues supported the protective effect of Z. zanthoxyloides phenol extract against diabetic damage.
Conclusion: In conclusion, total phenols of Z. zanthoxyloides exerted antidiabetic effects in alloxan-induced diabetic rats and protected pancreatic tissues from diabetic damage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
