【摘要】 目的用药效学方法筛选喘平方的提取工艺。方法观察不同提取工艺样品的镇咳和平喘作用。结果离子交换树脂法较酸水-乙醇提取法的平喘效果为好(P<0.01),单味提取与复方提取两种方法的平喘效果相差不大(P>0.05)。结论离子树脂法是较佳的提取工艺。更多还原

【Abstract】 Objective To select the optimal exacting process for Chuanping prescription (CP).Methods The anti- and the anti- asthma ticanti effects of extracts obtained by different extracting processes from CP were observed.Results The anti- asthmatic effect of extract obtained by ion exchange resin(IER) method was better than that by acid- liquid- extraction alcohol- precipitate method (ALEAP) (P < 0.01).The difference between the extract from single herb and that from the prescription was insignificant.Conclusion IER method is the better method for the extraction of CP.更多还原
