ISOLATION CHEMICAL CHARACTERIZATION AND HYPOGLYCEMIC ACTIVITY OF ALANGIUM SALVIIFOLIUM WANG BARK IN ALLOXAN INDUCED HYPERGLYCEMIC RATSAbstract
Aim of the present study was to isolate and characterize the biochemical principle and investigate the hypoglycemic activity of bark of Alangium salviifolium Wang in Alloxan induced hyperglycemic rats. The bark of Alangium salviifolium barks were collected and dried in shade and subjected to extraction with petroleum ether, Chloroform and methanol. Each extracts were subjected to preliminary phytochemical analysis. Petroleum ether and Chloroform extract were subjected to chromatography. Two compounds were isolated and purified by alcohol then, subjected to physical and spectral studies. Spectral results revealed that isolated compounds may be phytosteroids. Hypoglycemic activity was performed by alloxan induced method. MEAS were administered orally to the hyperglycemic induced rats at the dose of 250mg/kg, 500mg/kg and 750mg/kg. Glibenclamide was used as reference drug. Then blood glucose levels were measured at the time interval of 30 mins, 1, 2, 3, 4 hrs and 8hrs by one touch glucometer. Then blood samples were collected from all rats and evaluated for biochemical parameter. Significant reductions in the blood glucose levels were observed. The dose of 750mg/kg exhibited more significant (P<0.001) hypoglycemic activity as compare to the doses 500mg/kg and 250mg/kg. The present study reveals that bark extracts of Alangium salviifolium can be used as hypoglycemic drug.
