To study the ability of tea polyphenol to lowering blood lipid and antioxidation in the aged rats.
The SD rats were divided into three groups, i.e., control group and two trial groups fed with 1% and 2% tea polyphenol for six weeks, respectively.
Tea polyphenol could reduce serum level of lipid peroxide and increase the ratio of high-density lipoprotein cholesterol (HDL-C) to total cholesterol (TC), and significantly lower serum level of lipid peroxide in rats. Activities of superoxide dismutase in red blood cells of rats fed with 2% tea polyphenol were significantly higher than those in control ones.
Tea polyphenol can enhance antioxidation in vivo in the aged rats.
研究茶多酚对老年大鼠的降血脂及抗氧化能力。
将SD大鼠分为三组，即对照组和两个试验组，分别给予1%和2%的茶多酚，持续六周。
茶多酚可降低血清脂质过氧化物水平，提高高密度脂蛋白胆固醇（HDL-C）与总胆固醇（TC）的比值，并显著降低大鼠血清脂质过氧化物水平。饲喂2%茶多酚的大鼠红细胞中超氧化物歧化酶的活性显著高于对照组。
茶多酚可增强老年大鼠体内的抗氧化作用。
