Abstract:
Objective:To optimize the extraction process of Shenqi Lixin capsules through pharmacodynamic evaluation combined with orthogonal experiments with multi-index comprehensive evaluation.Methods:The congestive heart failure(CHF) model was established by intraperitoneal injection of doxorubicin in rats,and the LVEDD,LVESD,FS and LVEF of CHF rats were used as the indicators to screen the extraction process of the samples (process A was with the whole decoction of herbs and process B was with heterophylla powder mixed with the other herbs after boiling).The single factor tests and orthogonal tests were used to optimize the extraction process by taking the contents of astragaloside and tanshinone ⅡA and the quality of the decocted material as the indices,and adding water amount,decocting times and duration as the influencing factors.Results:Pharmacodynamic experiments indicated that the improvement effects of the samples from process B on cardiac symptoms and cardiac function in CHF rats were better than that of the samples from process A.The other medicinal materials were decocted by 12-fold amount of adding water,and repeated for 12 times with one hour for each time.The average extraction rate of astragaloside and tanshinone ⅡA was 61.82% and 50.07%,respectively,which was proven by the verification experiments.The average weight of the decoction was 6.02 g.Conclusion:The optimized extraction process of Shenq Lixin capsules is scientific,reasonable,stable and reliable.
