摘　　要：目的:通过对药食同源材料组合(藤茶30%、桑叶15%、菊花15%、芦根10%、麦芽10%、甘草10%和淡竹叶10%)中二氢杨梅素进行提取工艺优化,为药食同源材料开发及浸膏粉的生产提供参考。方法:先对提取次数进行考察,再以浸泡时间、加水量和提取时间为影响因素,在单因素试验的基础上,采用L_(9)(3^(4))正交表进行正交试验,优化水提法提取药食同源材料组合中二氢杨梅素的条件。结果:加水量对药食同源材料组合中二氢杨梅素提取量和浸膏得率具有显著影响(P<0.05),综合考虑生产的成本、时效性与稳定性,水提工艺的最优条件为加水浸泡0.5 h,提取2次,第1次加水体积为其质量的10倍提取1.5 h,第2次加水体积为其质量的8倍提取1.0 h。在最佳条件下,65 g药食同源材料组合中二氢杨梅素提取量为3761.14 mg,浸膏得率为31.42%。结论:热水回流提取法可作为药食同源材料组合的提取方法,此法简单可行,效率高,结果准确,可用于药食同源材料组合中二氢杨梅素的提取工艺优化研究。Objective:The extraction process optimization study of dihydromyricetin in the combination of medicine and food homologous materials(Ampelopsis grossedentata 30%,mulberry leaf 15%,chrysanthemum 15%,reed root 10%,malt 10%,licorice 10%and light bamboo leaf 10%)was carried out to optimize its extraction process,in order to provide a scientific and theoretical reference for the development of medicine and food homologous materials and the production of extract powder.Methods:The times extractions was firstly investigated,and then the soaking time,water addition and extraction time were used as influencing factors to optimize the conditions for the extraction of dihydromyricetin from the combination of medicinal and food ingredients by aqueous extraction using L_(9)(3^(4)) orthogonal table based on a single-factor test.Results:The amount of water added had a significant effect(P<0.05)on the extraction of dihydromyricetin and the yield of infusion in the combination of medicinal and food ingredients.Considering the cost,timeliness and stability of the production,the optimal conditions for the water extraction process were 0.5 h of soaking with water with twice extractions,and the first extraction with the solution including 10 times water of its mass for 1.5 h and the second with 8 times water of its mass for 1.0 h.Under the control of these optimal conditions,the amount of dihydromyricetin extracted from 65 g of the combination of medicine and food homologous materials was 3761.14 mg,and the yield of infusion was 31.42%.Conclusion:The hot water reflux extraction method can be used as an extraction method for the combination of medicinal and food homologous materials.This method is simple,feasible,efficient,and accurate.It can be used to optimize the extraction process of dihydromyricetin in the combination of medicinal and edible materials.
