Anti-hyperglycemic and anti-inflammatory activities of polyphenolic-rich extract of syzygium cumini linn leaves in alloxan-induced diabetic rats

Abstract

In this study, anti-hyperglycemic and anti-inflammatory activities of polyphenolic-rich extract of Syzygium cumini leaves in alloxan-induced diabetic rats were determined. Diabetes was induced by a single intraperitoneal injection of alloxan (150 mg/kg body weight) in female Wistar rats. The rats were orally administered with 400 mg/kg free phenol, 400 mg/kg bound phenol, and 5 mg/kg metformin, respectively. On the 14th day of oral administration, the animals were sacrificed, anti-hyperglycemic and anti-inflammatory were assessed. Fasting blood glucose and glycated hemoglobin levels; homeostasis model assessment–insulin resistance scores, lipid peroxidation concentration, glucose-6-phosphatase activity, and all concentrations of anti-inflammatory studied in alloxan-induced diabetic rats were significantly (P
