Introduction
Diabetes mellitus represents a significant global health challenge, characterized by metabolic disturbances affecting carbohydrate, fat, and protein metabolism. The increasing prevalence of diabetes, projected to rise dramatically, has led to a search for effective treatment options that minimize adverse effects. This study investigates the antidiabetic potential of Clerodendrum phlomidis leaf extract, comparing it with the known antidiabetic herb Gymnema sylvestre and the standard drug Glibenclamide, using alloxan-induced diabetic rats as a model.
Antidiabetic Efficacy of Clerodendrum phlomidis
The study demonstrated that oral administration of Clerodendrum phlomidis leaf extract significantly reduced blood glucose levels in alloxan-induced diabetic rats while also restoring insulin levels. The extract enhanced insulin secretion, suggesting a regenerative effect on pancreatic beta-cells. The results revealed that Clerodendrum phlomidis exhibited comparable efficacy to Gymnema sylvestre and Glibenclamide in lowering blood glucose levels, indicating its potential as an effective herbal remedy for diabetes management.
Biochemical and Lipid Profile Improvements
The treatment with Clerodendrum phlomidis and Gymnema sylvestre also resulted in favorable changes in lipid profiles and biochemical parameters. Diabetic rats showed significant increases in serum cholesterol, triglycerides, and various lipoproteins. However, administration of the plant extracts normalized these levels, suggesting their beneficial role in ameliorating diabetes-induced lipid abnormalities. Additionally, parameters such as liver glycogen content and activities of crucial metabolic enzymes were restored to levels closer to healthy control rats.
Oxidative Stress and Antioxidant Activity
The oxidative stress associated with diabetes was evident through increased lipid peroxidation and decreased levels of antioxidant enzymes in the diabetic rats. Treatment with the herbal extracts facilitated an increase in reduced glutathione and normalized catalase activity, reflecting their antioxidant potential. This suggests that the antidiabetic effects of Clerodendrum phlomidis and Gymnema sylvestre may be partially mediated through their antioxidant properties, combating oxidative damage induced by hyperglycemia.
Conclusion
The findings of this study indicate that both Clerodendrum phlomidis and Gymnema sylvestre possess significant antidiabetic and antioxidant properties, effectively normalizing biochemical disturbances in alloxan-induced diabetic rats. The presence of active phytoconstituents in the leaf extracts underpins these effects, supporting their traditional use in managing diabetes. The superior results demonstrated by Clerodendrum phlomidis highlight its potential as a promising candidate for further research and clinical application in diabetes treatment.
