Objective:To optimize preparation process of Qiangxin capsule.Method:Orthogonal experiment and comprehensive scoring method were used to optimize water extraction technology;Forming process and production conditions were studied by multi-factor comparison.Result:Established an HPLC-ELSD method for determination of astragaloside Ⅳ.optimum extraction process was as follows:extracted 3 times with 9 folds the amount of water for 1.5 h each time;Ratio of excipients and optimum wetting agent when making particles of filling material in capsule were determined
relative humidity should be lower than 67%.Conclusion:This preparation process was reasonable and feasible
it could provide theory envidence for industrial production of Qiangxin capsule.
