摘要: 研究怀菊花总黄酮对自发性高血压大鼠(SHR)的降压作用及其机制。将SHR随机分为模型组、怀菊花总黄酮高、中、低剂量组和依那普利阳性对照组。采用无创血压计测定血压及心率,采用放射免疫法测定血浆内皮素(ET)、血管紧张素Ⅱ(AngⅡ)、醛固酮(ALD)、肾素活性(PRA)含量。结果表明怀菊花总黄酮能够降低SHR的血压(P<0.01)、心率(P<0.05)、血浆ET(P<0.05)、AngⅡ(P<0.01)、ALD(P<0.01)、PRA(P<0.01),其降压机制可能与改善内皮功能和抑制肾素-血管紧张素-醛固酮系统(RAAS)活性有关。

Abstract: To study the antihypertensive effects and mechanisms of total flavonoids of Flos Chrysanthemi (TFFC) on spontaneous hypertension rats (SHR).The SHR were randomized into 5 groups:model group,high-dose,middle-dose,low-dose group of TFFC and enalapril group.Blood pressure and heart rate were measured by Non-Invasive Blood Pressure Analyzer,the contents of plasma endothelin (ET),angiotensinⅡ (AngⅡ),aldosterone (ALD) and plasma renin activity (PRA) were determined by radio-immunity method.The results showed that TFFC can decrease blood pressure (P<0.01) and heart rate (P<0.05),decrease the contents of plasma ET (P<0.05),AngⅡ (P<0.01),ALD (P<0.01) and PRA (P<0.01).The antihypertensive effect of TFFC was possibly caused by improving the endothelial function and inhibiting the activity of renin-angiotensin-aldosterone system (RAAS).

Key words: total flavonoids of Flos Chrysanthemi, SHR, blood pressure, ET, AngⅡ, ALD, PRA
