Objective To optimize the extraction process parameters of seven herbs in Xiaoruzeng Capsules (XC). Methods The content of paeoniflorin, ferulic acid, hesperidin, imperatorin and ligustilide was determined by HPLC. The extraction rate of five kinds of index components, the dry extract yield of extracted herbs and the fingerprint similarity of extracts were comprehensively evaluated. The orthogonal experiment was carried out to investigate the effects of ethanol concentration, extraction solvent, extraction time and extraction times on the extraction process. The information entropy weighting method was used to determine the objective weight of each index, and the extraction process parameters of seven herbs in XC were optimized. Results According to the comprehensive scoring results, it was determined that the best extraction process of the preparation was to add six times the amount of 50% ethanol, and decocted two times for 2 h each time. The average score of the three batches of verification scores was 99.72, and the RSD was 0.24%. Conclusion The preferred process has high extraction rate, with good stability and repeatability, which is suitable for mass production of the preparation.
