ANTIOBESITY, ANTIHYPERLIPIDEMIC AND ANTIDIABETIC AGENTS OF PROTO-CATECHUIC ACID IN HIGH FATTY DIET ALONG WITH ALLOXAN INDUCED DIABETES

Aim: The present investigation was carried out by evaluating the effect of protocatechuic acid (PCA) on a high-fat diet (HFD) along with a low dose of alloxan-induced hyperglycemia in male Wistar rats. Methods: In the present study, administration of high fatty diet (HFD) for 45 days  along with low dose of alloxan (80 mg/kg) in rats on 30 days produced significant high fatty diet in the, body weight, low density lipoproteins (LDL), triglycerides (TG) and blood glucose levels while decreases the high density lipoprotein (HDL) and serum insulin level. Protocatechuic acid (PCA) was started to administered at a dose of 50, 100, 200 mg/kg (orally) on day 45 of HFD administration and continue further 45 days. Glibenclamide was used as reference standard. Results: Results of PCA shows a significant decreased in body weight, blood glucose level after 45 days of treatment in diabetic animals. Result also indicated to increase in serum insulin level. The result of lipid profile indicated to normalize after 45 days treatment with PCA in diabetic rats. All the results are compared with reference standard glibenclamide. Conclusion: From this result, it concludes that PCA decreases the body weight, blood glucose level dose-dependently indicated antidiabetic and antiobesity activity. Antidiabetic activity of PCA is associated with increased in the level of serum insulin.
