Abstract:
This research work is on the preliminary determination of active components in bitter leaf root (vernonia amygdalina) in the treatment of diabetes. Deficiency of hormone (insulin) causes diabetes mellitus, a disease due to too much sugar being present in the blood. This is because, without insulin in the body, the result is that sugar is extracted in the urine. Consequently, fat and proteins are readily converted to carbohydrates and finally, glucose eventually. The body reserves are used up and muscular weakness set in. This research work also is to critically look at the concept of diabetes mellitus causes, symptoms, types, anatomy, and physiology of the pancreas and the effect of vernonia amygdalina root on diabetes mellitus.
Also to provide adequate care for diabetes mellitus patients and to alleviate complications. Finally to determine the critical effect of different extracts of vernonia amygdalina root on wistar rats and to see the frequency on the curves. Alloxan (2, 4, 5, 6-tetraoxypyrimidine; 2, 4, 5, 6-pyrimidinetetrone) is a toxic glucose analogue, which selectively destroys insulin-producing pancreatic β-cells and causes a non-insulin-dependent diabetes mellitus (NIDDM), when administered to animal species. In this study, the protective effects of bitter leaf root on glucose tolerance test and alloxan induced diabetes were evaluated. An effort was also made to investigate the acute toxicity (LD50) of the extracts and the qualitative presence of phytoconstituents in the extracts.
Male wistar albino rats (weighing 100–170g) were studies for glucose tolerance tests and alloxan-induced diabetes. Ethanol, methanol, hexane, and ethyl acetate extracts of bitter leaf root were selected for anti-diabetic activity. Blood glucose levels were estimated at different day intervals on the treatment with bitter leaf root extracts and glibenclamide. These levels were compared with those of the diabetic control group. Phytochemicals analysis of bitter leaf root revealed the presence of flavonoids, carbohydrates, steroids, tannins, and phenolic compounds. All the extracts of bitter leaf roots exhibited significant anti-diabetic effects in both the experimental models of diabetes mellitus. The results justified the traditional use of roots in the treatment of diabetes.
