| 摘 要： | 目的 采用正交设计法选择黄花远志的最佳提取方案.方法 用甲醇、乙醇、丙酮、乙酸乙酯和水进行单因素实验,选择最佳提取溶剂.采用L_(16)(4~5)正交实验没计对黄花远志进行回流提取.以提取浸膏干粉质量为评价指标分析回流次数、回流时间、料液比、溶剂浓度和回流温度5个因素对提取率的影响.结果 最佳提取工艺为95%乙醇,料液比1:5,75℃下回流提取3次,1.5 h/次,提取率为11.89%.结论 该提取方法操作简便,结果可靠.

| Abstract: | Objective To explore the optimal conditions for extraction of Polygala fallax Hemsl. Methods Various trials were conducted to extract P. Fallax Hemsl. With L_(16) (4~5) orthogonal experiments. Results The optimal experimental parameters for extraction were 95% ethenol, dosage-liquor ration at 1:5, three-times extraction at 75℃, 1.5 hours for each extraction, and extraction rate at 11.89%. Conclusion Orthogonal test is convenient and accurate in extracting P. Fallax Hemsl. |
