英文摘要:

      Objective To use orthogonal experimental design, combined with analytic hierarchy process (AHP) and criteria importance through intercriteria correlation (CRITIC), optimize the extraction process of the composite beverage containing Codonopsis pilosula, Astragalus membranaceus, Poria cocos. Methods The weight coefficients of the indicators including the content of total saponin, total flavone, total polysaccharide and dry extract rate were assigned by AHP, CRITIC, and AHP-CRITIC weighting analysis. The orthogonal experimental comprehensive scoring method was applied to analyze the results of the orthogonal experiment and optimize the extraction process parameters of the composite beverage containing Codonopsis pilosula, Astragalus membranaceus, Poria cocos. Results The weight coefficients determined by AHP-CRITIC were scientifically reasonable. The optimal extraction process selected based on the comprehensive evaluation results obtained by combining weight coefficients with orthogonal experimental scoring method as follows: Extract the medicinal materials twice with 18 times the amount of water, each extraction time for 60 minutes. Under the optimal extraction process conditions, the total saponin content of the composite beverage was 32.21 mg/100 g, the total flavonoid content was 41.48 mg/100 g, the total polysaccharide content was 6.245 mg/100 g, and the paste yield was 16.34%. Conclusion The preferred extraction process is easy to operate, stable, and has a high extraction rate, which can be used for the preparation of the composite beverage containing Codonopsis pilosula, Astragalus membranaceus, and Poria cocos.
