    Abstract:Objective:To optimize the alcohol-extraction process for astragalus membranaceus (Fisch.) Bge.in Xiao Jingtong capsule.Methods:The extraction process was studied by orthogonal design with the contents of astragaloside A and dried alcohol decocting rates.Results:The optimum alcohol-extracting condition was A3B1C3D3,that is adding 8 times amount of 70%alcohol for three times and each for two hours.Conclusion:This method is simple, stable, and suitable for industrial produce.
