摘要: 参照《保健食品检验与评价技术规范 2003版》对γ-氨基丁酸(GABA)超微绿茶粉进行辅助降血压功能评价。动物实验设低、中、高(0.83、1.67、5.00g/kg)3个剂量组,分别相当于人体推荐剂量的5、10、30倍。另设高血压模型对照组和正常动物高剂量对照组。经口连续给予样品30d,结果显示:高剂量组(5.00g/kg)的血压从第2周后开始一直低于SHR(自发性高血压大鼠,Spontaneously Hypertensive Rat,SHR)模型对照组,并有显著性差异,而对SHR大鼠心率无显著性影响;同时样品对正常动物的血压及心率均无影响。结果表明,γ-氨基丁酸超微绿茶粉对高血压动物具有辅助降血压功能。

Abstract: According to “inspection and evaluation of health food (2003 edition)”, the anti-hypertensive activity of GABA green tea powder was evaluated. Animal experiments with low, medium, high dosage group were 0.83g/kg, 1.67g/kg and 5.00g/kg, the equivalent of human recommended doses of 5, 10, 30 times. A hypertension model group and normal control group and high dose animals group were set. The animals were orally feed with the green tea powder for 30 days. The experimental results showed that the high dose group (5g/kg) of SHR(Spontaneously Hypertensive Rat) rats blood pressure at the second week began lower than that of model group, and the difference is significant, and each animal group’s heart rate had no significant difference, and the samples have no effect on blood pressure and heart rate in normal animals. In our experimental conditions, the GABA green tea powder showed anti-hypertensive activity.
