ABSTRACT
Objective The extraction process of Shenxi Oral Liquid by exploring the optional extraction process parameters based on determining the index weight. Methods Using the contents of cyasterone, ginsenosides Rg1, Re, Rb1, panaxadiol, ratio of dry extraction, total polysaccharides, and total peak area as comprehensive evaluation indexes, the weighting coefficient in eight synthetic evaluation indexes was determined by analytic hierarchy process (AHP), criteria importance through intercriteria correlation (CRITIC) method, and mixed weighted AHP-CRITIC. Compared mixed weighting method and single weighting method, the optimal parameters of compound extraction process were optimized by orthogonal test. Results Mixed weighted AHP-CRITIC was more scientific, reasonable, and comprehensive than the single weighting method. According to the weighting coefficient determined by comprehensive evaluation, the optimal process parameters were as follow compound herbs plus nine times of water, extracting three times, each for 80 min. The mean of three batches of comprehensive evaluation was 99.06 and RSD value was 0.18%. Conclusion AHP combined with CRITIC could be used to establish weighting coefficient of the compound formula extraction process and the optimized process of extraction had been verified to be reasonable, stable, and reproducible, which could be used for industrial production.
