Abstract:
Pu-erh tea is a unique post-fermented tea processed from tender leaves of Camellia assamica. Characteristic component puerins were produced during the microbial fermentation process.This study focuses on the therapeutic effect and mechanism of puerinⅠ(P1) in Pu-erh tea on ApoE-/- mice with dyslipidemia and diabetes. It was found that P1 could significantly decreased total cholesterol (TC), triglyceride (TG) and fast blood glucose (FBG), and markedly improved impaired glucose tolerance (IPGTT) and insulin sensitivity (ITT) in hyperlipidemic and hyperglycemic ApoE-/- mice. Further experiments proved that P1 reduced FBG and plasma TG levels by inhibiting intestinal α-glycosidase enzymes activity and by activating low-density lipoprotein receptor respectively. This study confirmed the therapeutic effect and mechanism of P1 on ApoE-/- mice with diabetes and hyperlipidemia. Based on the good efficacy of this compound, P1 could be used as a new drug to treat the disorder of glycolipid metabolism.
