摘要：目的:采用熵权法优选湖北海棠叶中总黄酮的提取工艺。方法:以浸膏得率、总黄酮及根皮苷含量为综合评价指标,选取乙醇体积分数、溶剂用量及提取时间为影响因素,应用熵权法确定各因素的客观权重,通过Matlab编程实现提取工艺的正交试验优选。结果:最佳提取工艺为10倍量70%乙醇回流提取3次,每次1 h。结论:熵权法可用于中药提取工艺优选,使用Matlab编程可减少正交试验计算量。
Objective： To optimize extraction technology of total flavonoid from Malus hupehensis by entropy-weighting method. Method： With yield of extract, the content of total flavonoid and phloridzin as comprehensive evaluation indexes, the concentration and dosage of solvent, extraction time were selected as factors, weight of which were determined by entropy-weighting method, extraction technology was optimized by orthogonal test which was realized by Matlab. Result： Optimum extraction technology was： reflux extracted 3 times with 10 folds the amount of 70% ethanol, 1 h each time. Conclusion： Entropy-weighting method eould be used in optimizing of extraction technology for traditional Chinese medicine, calculation amount of orthogonal test could be reduced by Matlab programming.
