Antioxidant effect of tea polyphenols on oxidative stress mice
Oxidative stress can cause lipid peroxidation,induce cell apoptosis,and damage cellular genetic material,thereby affecting the normal growth and development process of animals.This article induced oxidative stress in mice fed with tea polyphenols.By monitoring the weight and food intake of the induced mice,serum and liver antioxidant indicators were measured to study the alleviating effect of tea polyphenols on oxidative stress in mice.The results showed that before oxidative stress induction,there was no significant difference in weight and food intake among the groups of mice;after oxidative stress induction,the content of superoxide dismutase and total antioxidant in the serum of the stress group significantly decreased.Tea polyphenols could effectively increase the serum antioxidant level.At the same time,the content of catalase and superoxide dismutase in the liver of the stress group mice decreased,while the content of malondialdehyde increased.Tea polyphenol treatment could increase the content of catalase and superoxide dismutase in the liver of mice,this indicated that tea polyphenols could effectively increase serum antioxidant levels,protect mouse liver,and reduce oxidative stress damage caused by diquat.The purpose was to provide a reference basis for further research on how tea polyphenols alleviate oxidative stress in animal husbandry.
