Reducing blood lipid behavior in vivo based dark brick tea intake

ABSTRACT

Dark brick tea, a unique kind of dark tea has a history of more than 100 years in China. In this paper, 1 and 10 years old dark brick tea were used to regulate blood lipid. The results showed that dark brick tea could significantly reduce the total cholesterol (TC) and triglyceride (TG) levels in serum and liver homogenate. It also significantly increased the level of high-density lipoprotein cholesterol (HDL-C). In addition, dark brick tea can enhance the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in rats, reduce the content of malondialdehyde (MDA), promote the activities of lipoprotein lipase (LPL) and liver lipase (HL) in rats, and effectively reduce blood lipid levels. In conclusion, the experimental results of this study will provide a scientific basis for the lipid-lowering effects of black brick tea with a theoretical basis for its further development and utilization in the form different products.
