OBJECTIVE: To find out the hypoglycemic and hypolipidemic activity of an ethanolic extract of the aerial part of Salvadora oleoides Decne in euglycemic and alloxan-induced diabetic albino rats. MATERIALS AND METHODS: Diabetes was induced in albino rats by administration of alloxan monohydrate (120 mg/kg, i.p.). Normal as well as diabetic albino rats were divided into groups (n = 6) receiving different treatments: vehicle (control), ethanolic extract (1 g and 2 g/kg b.w), and standard antidiabetic drug tolbutamide (0.5 g/kg b.w.). Blood samples were collected by cardiac puncture and were analyzed for blood glucose and lipid profile on days 0, 7, 14, and 21. RESULTS: The ethanolic extract of S oleoides produced significant reduction (P < 0.001) in blood glucose and also had beneficial effects (P < 0.001) on the lipid profile in euglycemic as well as alloxan-induced diabetic rats at the end of the treatment period (21(st) day). However, the reduction in the blood glucose and improvement in lipid profile was less than that achieved with the standard drug tolbutamide. CONCLUSION: We concluded that an ethanolic extract of S oleoides is effective in controlling blood glucose levels and improves lipid profile in euglycemic as well as diabetic rats.
