Antihyperglycemic and hypolipidemic effects of Melothria maderaspatana and Coccinia indica in Streptozotocin induced diabetes in rats

Antihyperglycemic and hypolipidemic effects of ethanol extract of aerial parts of Melothria maderaspatana and Coccinia indica were evaluated in STZ induced diabetes in Sprague–Dawley rats. The rats were concurrently treated with 100 or 200 mg/kg b.w. p.o. for 14 days. The changes in fasting blood glucose level and body weight were measured in 5 days interval. After 14 days experimental period, rats were sacrificed by cervical decapitation, blood and liver samples were collected. Biochemical estimation of plasma glucose, cholesterol, triglycerides, LDL, HDL, SGOT, SGPT and ALP were done from blood sample. The liver glycogen content was estimated using standard procedure from homogenized liver sample. Administration of EEMm or EECi to STZ-diabetic rats caused significant antihyperglycemic and hypolipidemic effects (p < 0.001). The extracts were also found to be significantly effective (p < 0.001; p < 0.05) on recovery of altered biochemical parameters and decreased body weight in treated animals. Glibenclamide (0.5 mg/kg b.w.) was used as standard in present study.
