ABSTRACT
Objective To explore the regulatory effect of apigenin on the blood pressure of the spontaneous hypertension rat(SHR) rats and the possible mechanism.Methods The case groups of rats were fed with different dosage of apigenin(0.03,0.05,0.11 g/kg) by gavage for 4 consecutive weeks,while the control groups were treated with equal cubage of oil.The body weight,heart rate,blood pressure were measured every week.Results After 4 weeks of treatment with apigenin,the blood pressure of SHR in all doses groups decreased significantly;besides,apigenin could reduce the content of ET-1 and AngII,however,it didn't change NOS activity.Conclusion Apigenin has a regulatory effect on blood pressure,its lowest effective dose is 0.03 g/kg bw and it may decrease the blood pressure through reducing the content of ET-1 and AngII,not through the NO/NOS pathway.
