Clausena lansium (Lour.) Skeels (Wampee) is widely grown in China and considered as a healthy fruit. Its leaves are also considered as traditional herbs. This study analyzed polyphenol compounds in polyphenol extracts of the leaves C. lansium (lour.) Skeels (PEL) and investigated the protective effect of PEL against hyperglycemia and hyperlipidemia in T2DM rats. The result showed that PEL is composed mainly of gallic acid, chlorogenic acid, coffee acid, ferulic acid, and rutin. PEL could obviously relieve some symptoms of T2DM rats, including emaciation, hyperhidrosis, polyphagia, diuresis, liver swelling, kidney, and pancreas hypertrophy, as well as reduce fasting blood glucose. Moreover, the supplementation of PEL significantly ameliorated lipids disorder and protected liver in T2DM rats, including fat accumulation, improvement of lipid distribution and hepatocyte protection. These results indicate that the Oral of PEL have potential effects of against hyperglycemia and hyperlipidemia in diabetic disorders. PRACTICAL APPLICATION The leaves Clausena lansium (lour.) Skeels is rich in polyphenol and other ingredients. In this research, the preliminary study shows that PEL can reduce fasting blood glucose and improve lipids disorder in rats, which will bring to diabetic patients a way to improve the disease and enhance the quality of life. The PEL therefore can be used for the production of pharmaceutical raw materials and the design of novel functional foods by simple conversion.
