| 摘 要： | 以左旋紫草素、羟基萘醌总色素的提取率为评价指标,对比闪式提取、回流提取、超声提取对紫草中有效成分的提取效果,采用正交设计综合评分法对闪式提取的工艺参数进行优化。结果表明,闪式提取法提取效率最高,优选的闪式提取最佳工艺为95%乙醇提取3次,每次90 s。在此工艺条件下左旋紫草素、羟基萘醌总色素提取率分别为93.16%,93.89%,出膏率为5.16%。闪式提取法适于紫草有效成分的提取,通过正交试验设计优选的紫草闪式提取工艺稳定、切实可行。

| Abstract: | The extraction of functional components from radix of Arnebia euchroma was optimized using orthogonal design based on the extraction yields of shikonin, and hydroxyl-naphthoquinone pigments. The data processing was carried out with the multiple guidelines grading method for optimizing the extraction condition. Compared with the traditional method (refluxing and ultrasonic extraction), the flash extraction method was more efficient. The optimal conditions were as follows: 95% ethanol extract 3 times with 90 s for each. Under these conditions, the extraction yields of shikonin, and hydroxyl-naphthoquinone pigments were 93.16%, 93.89%, respectively, and the dry extract rate was 5.16%. In conclusion, the result showed that the flash extraction technology was appropriate, stable and feasible. |
