The glucose lowering effect of zornia gibbosa span extracts in diabetic rats

Abstract

Objectives: Diabetes mellitus is a chronic, lifelong condition that affects our body physiology. Untreated diabetes mellitus causes diseases such as diabetic retinopathy, diabetic nephropathy and diabetic neuropathy, auto immune diseases, polyuria, polydipsia, loss of weight, and cardiovascular diseases. The use of medications for the treatment of diabetes mellitus causes adverse effects with long-term use, and sometimes leads to death. Today, researchers are working on the discovery of new anti-diabetes drugs from plants with low or no adverse effects. From this point of view, the present work was conducted to evaluate the anti-diabetic activity of Zornia gibbosa Span. Materials and Methods: This acute toxicity study was conducted for ethyl acetate and ethanol (70%v/v) extracts of Z. gibbosa as per OECD guidelines. The anti-diabetic activity of selected plant extracts were tested using alloxan-induced diabetes in a rat model. Results: No mortality was observed in the administered doses of Zornia gibbosa Span extracts. The tested extracts significantly (p≤0.01) restored the physiologic changes that occurred due to the alloxan-induced diabetes mellitus. The hydroalcoholic extracts at 500 mg/kg body weight concentration showed more activity compared with other extracts at different concentrations along with standard drug (glibenclamide). Zornia gibbosa significantly decreased glucose concentrations and restored the altered enzymes levels caused by damage to different organs by diabetes. Conclusion: The results of the present study indicate that Z. gibbosa has a significant anti-diabetic activity. Therefore, it may be capable of use as an alternate medicine along with allopathic medicine in the treatment of diabetes as well as its health problems.
