ABSTRACT

<p><b>OBJECTIVE</b>To compare the actions of the three flavone ingredients in choerospondias axillaris on arrhythmias Induced by aconitine.</p><p><b>METHOD</b>Langendorff perfuse was applied in the experiment, the antiarrhythmic action was to study by using aconitine on the the isolated heart; The antiarrhythmic action of the three flavone ingredients in choerospondias axillaris was to study by using i.v. aconitine in rat to induce arrhythmias.</p><p><b>RESULT</b>Compared with the NS group, sample 1 and sample 2 both significantly prolonged the beginning time of VF of isolated heart and increased the dosage of aconitine, sample 3 reduced the beginning time of VF of isolated heart and decreased the dosage of aconitine, sample 1 and sample 2 both greatly prolonged the beginning time of VE, VT, VF, HA; sample 3 greatly reduced the beginning time of VT,VF. The actions of the three samples were in a concentration-dependent way.</p><p><b>CONCLUSION</b>Sample 1 and sample 2 both resisted the occurrence of arrhythmias induced by aconitine, sample 3 markedly promoted the occurrence of arrhythmias induced by aconitine.</p>
