摘要
目的:观察动物对茶多酚的急性和慢性的毒性反应。方法:小鼠分5组,剂量比值为1∶0.8,连续灌胃7d。按Blis法计算茶多酚LD50。大鼠分对照组,茶多酚高、中、低剂量组(0.4g/kg·d-1、0.6g/kg·d-1和0.8g/kg·d-1),连续灌胃90d。结果:茶多酚LD50为2.499g/kg。动物长期服用茶多酚未出现体重、血常规、肝肾功能及脏器组织的毒性变化。结论:茶多酚属低毒性,对大鼠0.8g/kg·d-1的剂量相当于成人用量的100倍以上。
Objective:The study was to observe the acute and chronic toxicity of Tea Polyphenols(TP).Methods:the mice were divided into five groups and TP was given orally for 7 days.The method of Bliss was used to determine the LD 50 of the TP.The rats was divided into control group,TP high dosage group,TP middle dosage group and low dosage group(0.4,0.6,0.8g/kg·d -1 ) to observe the chronic toxicity.Result:The LD 50 of TP is 2.499g/kg.The rats have showed no toxicity reaction in weight,blood,the internal organs,liver and kidneys function after the using of the drug.Conclusion:The TP has low toxicity,the dosage of 0.8g/kg.d -1 in rat is equivalent to 100 times of the dosage used in clinic for an adult.It indicates that the clinical using of TP is safe.
