Karst)methanol extract. T. aphylla leaves extract was administered intraperitoneally(100 mg,250 mg and 400 mg/kg body weight per day) to diabetic Wister rats for 21 days. The various parameters were studied including fasting blood glucose levels, haemoglobin and glycosylated haemoglobin.Results: The treatment groups with the extract at three dose levels expressively abridged the intensities of blood glucose and Glycosylated Haemoglobin. The earlier detected reduced level of plasma haemoglobin of the diabetic rats was raised to near normalcy with treatment of extract.Conclusions: The results of the current study confirm that the leaves extract of T. aphylla are nontoxic and have antidiabetic nature.展开更多
