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.
