This study evaluated the anti-diabetic and hepatic protective effect of the aqueous extract of the Aloe perryi (AP) in streptozotocin-induced diabetic rats. Rat were divided into control, diabetic, diabetic + glimepiride, diabetic + AP (150 or 300 mg/Kg) groups. AP (300 mg/Kg) alone lowered fasting serum glucose levels but increased insulin levels and HOMA-β. At both doses, AP significantly decreased hepatic levels of CHOL and LDL-C and reduced serum levels of TGs, CHOL, and LDL-C, without altering levels of HDL-C in the diabetic rats. Also, they improved liver architectures and reduced serum levels of ALT and AST. Concomitantly, they suppressed hepatic levels of MDA, and increase hepatic levels of SOD, GSH, CAT, and GPx. Except for lipids, the effect of the extract on all other parameters was more profound with the higher dose of the extract. In conclusion, AP extract exerts hypoglycaemic, insulin-releasing, and hepatic antioxidant potentials in diabetic rats.
