目的:优选桑寄生中槲皮素的醇提工艺。方法:采用高效液相色谱法,应用正交试验,对影响桑寄生中槲皮素的提取效率的各因素进行考察。结果:以乙醇浓度为95%乙醇回流提取两次;提取时间分别为1.5 h、1.0 h;乙醇用量分别为1:8、1:4为最佳提取工艺。结论:该工艺合理可行。
Objective: To optimize the alcohol extraction process of quercetin from Loranthaceae. Methods: The factors affecting the extraction efficiency of quercetin in mulberry was investigated by high performance liquid chromatography and orthogonal test. RESULTS: The extraction was carried out twice with ethanol at a concentration of 95% ethanol; the extraction times were 1.5 h and 1.0 h, respectively; the ethanol dosages of 1:8 and 1:4 were the best extraction techniques. Conclusion: This process is reasonable and feasible.
