Qualitative phytochemical screening tests were conducted to identify the chemical constituents of the plants. Healthy swiss albino mice of either sex (25 g-30 g) with no prior drug treatment were used for the present study. An acute toxicity study was carried out according to the 2008 organization for economic cooperation and development guideline 425. The effects of extracts of the plants on fasting blood glucose level and body weight of diabetic mice were evaluated using repeated dose antidiabetic activity test model. Fasting blood samples were collected from the control and test groups weekly to monitor blood glucose levels. Changes in body weight were also recorded weekly.
