In order to optimize the extraction process of Zhuang medicine Sangshuntang granules, a study was conducted to determine the weight coefficients of the indicators by comparing the Analytic Hierarchy Process (AHP), the Weight Determination Method Based on Index Correlation (CRITIC), and the AHP - CRITIC mixed weighting method. The orthogonal test was conducted to compare the comprehensive scores of each indicator component (total mass fraction of geraniol, total mass fraction of rosmarinic acid, paste rate), and the extraction process of Zhuang medicine Sangshuntang granules was obtained by boiling and extracting compound decoction pieces with water three times, adding 12 times the volume of the mass of the herb in water for the first time, and 10 times the volume of water for the second and third times, respectively. The total amount of puerarin and rosmarinic acid in the validation experiment were 340.84 and 22.86 mg, respectively, with a paste yield of 14.59%. The AHP - CRITIC mixed weighting method combined with orthogonal experiments determined the stable and feasible extraction process of Zhuang medicine Sangshuntang granules, which can provide reference for industrial production.
