Abstract:The aim of the study was to investigate the auxiliary hypolipidemic and antioxidative activity of the Hongzhuan tea. According as the animal experimental methods from , the related indicatorsin hyperlipidemia rats were tested after the rats were given by oral administrations of Hongzhuan tea aqueous extracts with different doses of 88.75 mg/(kg·d), 177.5 mg/(kg?d) and 355 mg/(kg?d). The results showed that the serum TG was significantly reduced in rats treated with medium and high dose groups(p<0.01), while the low dose group had no significant difference compared with the control group. The serum total cholesterol (TC) in the three groups had no significant difference. The serum high-density lipoprotein cholesterol (HDL-C) significantly increased in rats administrated with medium dose group (p<0.05), but had no significant difference in low and high dose groups. The serum low-density lipoprotein cholesterol (LDL-C) was significantly reduced in rats administrated with high dose group (p<0.05), but had no significant difference in low and medium dose groups. According to the judging rules, the results showed that the Hongzhuan tea aqueous extracts assisted hypolipidemic function, reducing serum cholesterol function, and reducing serum triglyceride were positive the animal experiment. The activities of SOD (p<0.05) and GSH-Px (p<0.01) in liver were significantly increased in medium and high dose groups, while the concentration of MDA (p<0.05) was significantly reduced which showed that its antioxidative activity was positive.
