[Abstract]
Objective To optimize extraction technology of Tongmai Yangxin prescription. Methods Animal arrhythmia on mice by chloroform and isolated thoracic aortic ring of rats to observe effects of pharmacological activity and contents of glycyrrhizic acid were used to optimization and verify the extraction process of Tongmai Yangxin prescription. Results Optimum extraction conditions were as follows: heating refluxing extracted 2 times with the amount of 60% ethanol for 8 times 1.5 hours and 6 times 1 hour. Conclusion Tongmai Yangxin prescription in the optimized extraction technology with significant pharmacological activity, showing the dose-effect relationship.
