Objective To apply orthogonal experimental design and combine the standard relation and entropy weight-technique for order preference by similarity to an ideal solution (TOPSIS) model to screen the modern extraction process of Qianghuo Shengshi Decoction (羌活胜湿汤, QSD). Methods Nine samples were prepared by orthogonal experimental design with the amount of water, extraction time and frequency as the investigating factors, and the contents of prim-O-glucosylcimifugin, ferulic acid, liquiritin, 5-O-methylvisammioside, glycyrrhizic acid, notopterol, osthole, columbianadin, and fingerprint similarity, as well as the dry paste rate of the samples, were taken as the evaluating indexes to calculate the standard relation of each sample index, and then used in entropy weighting to determine the weights of the indexes to calculate the composite scores, and then calculated and ranked by the relative proximity of the samples with the standard sample by using the TOPSIS model to screen for the optimal extraction process combined with the composite scores. Results The optimal extraction process was determined by the entropy weight-TOPSIS model by adding 10 times water and extracting twice for 30 min each time, the mean value of the combined score of the three batches of validation samples was 85.53%, the RSD value was 1.74%, and the process was stable and feasible. Conclusion An integrated strategy combining standard relation and entropy weight-TOPSIS model can be used to optimize the modern extraction process of classical prescriptions with a stable and reliable process, and this strategy can be used as a reference for the research of other classical prescriptions.
