title: Antihyperglycemic and hypolipidemic activity of methanolic extract of Amaranthus viridis leaves in experimental diabetes.
abstract: To investigate the antihyperglycemic and hypolipidemic effects of methanolic extract of leaves of Amaranthus viridis (MEAV) in normal and Streptozotocin (STZ) induced diabetic rats. The anti-hyperglycemic and hypolipidemic activity of methanolic extract of leaves of Amaranthus viridis was evaluated by using normal and STZ induced diabetic rats at dose of 200 mg/kg and 400 mg/kg by mouth per day for 21 days. Blood glucose levels and body weight was monitored at specific intervals, and different biochemical parameters, serum cholesterol, serum triglyceride, high density lipoprotein, low density lipoprotein, very low density lipoprotein were also assessed in the experimental animals. Histology of pancreas was performed. The statistical data indicated a significant increase in the body weight, decrease in the blood glucose, total cholesterol and serum triglycerides after treatment with MEAV. High density lipoprotein (HDL) cholesterol level was significantly increased when treated with extract. Histologically, focal necrosis was observed in the diabetic rat pancreas; however, was less obvious in treated groups. The MEAV has beneficial effects in reducing the elevated blood glucose level and body weight changes, and improves the lipid profile of STZ induced rats.
