Objective To provide a reference for the industrial production of the extraction process of Compound Baihuang Xiere Zhili Tablets (CBXZT) by exploring the optional extraction process parameters based on determining the index weight. Methods With the extraction capacity of anemoside B4, berberine hydrochloride, aesculin, aesculetin, scopoletin, and ratio of extraction as comprehensive evaluation indexes, the weighting coefficient in six synthetic evaluation indexes was determined by Analytic Hierarchy Process (AHP), Criteria importance through intercriteria correlation (CRITIC) method, and mixed weighted AHP-CRITIC. And ethanol-extracting process was optimized by orthogonal test. Results The excellent linearity with correlation coefficients were 121.1-1211.0, 82.2-822.0, 22.3-223.0, 15.42-154.2, and 1.6-16.0 μg/mL, r of 0.999 7-0.999 9 was obtained, and the average recoveries of the five compounds were 99.23%-100.63% with all RSD values less than 3.0%. Mixed weighted AHP-CRITIC was more scientific, reasonable, and stable than AHP and CRITIC. The optimal process parameters were confirmed to be decocting for thrice with 2 h in each by eight times the amount of 60% ethanol, according to the weight coefficient determined by comprehensive evaluation. Conclusion These optimized technologies are stable, feasible, and suitable for standardized production of CBXZT. The weight coefficient determined by mixed weighted AHP-CRITIC was objective, real and could reflect the compound compatibility information. These optimized technologies are stable, feasible and suitable for standardized production of CBXZT.
