The present study was aimed out to investigate the effects of different solvent extracts from Ocimum tenuiflorum L. leaves on lipid profile, liver function, and kidney functions of streptozotocin-induced diabetic rats and toxicology assessment. In this study Ocimum tenuiflorum leaves solvent crude extracts were used for an acute test for 14th days. Diabetes was induced in Spargue-Dawley rats by intraperitoneal (i.p.) injection of streptozotocin. All the diabetic rats were under treated by oral admonition of extracts (1000 mg/kg) for fourteen days. After 14th days of treatment blood was withdrawn for biochemical and haematological tests. Kidney, pancreas and liver discarded for histopathology assessment of toxicity effect on organs. Blood glucose level and other biochemical measurements in streptozotocin-induced rats compared with the control group showed fluctuating levels in a different parameter. Histological analysis of tissues indicated there were no adverse changes in the liver, kidneys, and pancreas compared to the control group. According to our result, Ocimum tenuiflorum methanol leaf extract as a medium polarity solvent extract had possibly exerts of an antihyperglycaemic effects through major bioactive compounds that be able to control diabetes. A clinical study is needed to confirm the antidiabetic potential of this plant.
