摘　　要：以紫草为研究对象,采用单因素实验考察了提取温度、料液比、乙醇体积分数对紫草总萘醌提取量的影响;在单因素实验的基础上,采用正交实验优化了紫草总萘醌的加热回流提取工艺。结果表明:在提取时间为2 h、提取温度为90℃、料液比为1∶50(g∶mL)、乙醇体积分数为90%的最优条件下,紫草总萘醌提取量可以达到30.03 mg·g^(-1)。该研究为紫草药用植物资源的开发利用提供了参考。Using Arnebia euchroma as a research object,we investigated the effects of extraction temperature,solid-liquid ratio,and ethanol volume fraction on the extraction amount of total naphthoquinones from Arnebia euchroma by single-factor experiments.Moreover,we optimized the heating reflux extraction process of total naphthoquinones from Arnebia euchroma by orthogonal experiments on the basis of single-factor experiments.The results show that the extraction amount of total naphthoquinones from Arnebia euchroma reaches 30.03 mg·g^(-1) under the optimum conditions as follows:the extraction time of 2 h,the extraction temperature of 90℃,the solid-liquid ratio of 1∶50(g∶mL),and the ethanol volume fraction of 90%.This study provides a reference for the development and utilization of medicinal plant resources of Arnebia euchroma.
