[Abstract]
Effect of canthin-6-one (Can)(an alkaloid extracted from Zanthoxylum dimorphophylhum Hemsl. var. spinifolium Rehd. et Wils.) on experimental arrhythmia induced by aconitine, ouabain and ischemia/reperfusion was studied. Can (5, 10, 20 mg/kg, ig) was shown to increase the threshold dose of causing ventricular ectopic, ventricular tachycardia, ventricular fibrillation; decrease the incidence of arrhythmia induced by ischemia/reperfusion, shorten duration of ventricular arrhythmia and eliminate the incidence of ventricular fibrillation. These results suggested that canthin-6-one has a protective effect on experimental arrhythmia.
