Normal vehicle control animals were found no change in their body weight but diabetic control rats showed 11.19% reduction in the body weight. The treatment with Extract (at 100 & 200 mg/kg b.w.) showed less change in the body weight (7.11% & 4.43% respectively) compared with the diabetic control.
The effect of ethanolic extracts of Jasminum grandiflorum in alloxan induce diabetes is shown in table-7.6. The intraperitonial administration of alloxan elicited significant hyperglycaemia in rats. Pre-treatment with extract at dose 100 & 200mg/kg and glibenclamide at dose 5mg/kg elicited significant inhibition of alloxan induced hyperglycamia. Almost similar and significant inhibitory effect was observed on 7th day and 14th day.
The Results were compared with glibenclamide was more effective in reducing blood glucose level in normal as well as negative control
