【Abstract】 Objective:To optimize the water extraction process of Xuanfei Jiedu capsule(宣肺解毒胶囊) by Central Composite Design-Response Surface Method.Methods:The liquid ratio of material and the extraction time were taken as the observation factors,the OD value of the extraction rate of forsythiol glycosides and the paste yield after "normalization" was taken as the investigation index.Using design-expert 8.0.6.1 software Design experiment,the mathematical model between the factors and the effect surface was established by using multiple linear equations,the contour map and effect surface map of the interaction between the factors were drawn,and the optimal extraction process of Xuanfei Jiedu capsule was optimized and verified.Results:The optimal extraction conditions were as follows:the ratio of solid to liquid was 9 mL/g,the first extraction time was 170 min,and the second extraction time was 80 min.The predicted OD value was 1.16.After verification,the actual OD value was 1.124,which was-3.6% different from the predicted value.Conclusion:The optimal process condition of Xuanfei Jiedu capsule water extraction is stable,the index is the largest in the controllable range,and it is feasible in practice.更多还原
