摘要
目的:优选白头翁的最佳醇提工艺。方法:以测定白头翁中皂苷B4提取率作为考察指标,采用L9(34)正交试验,考察乙醇浓度、浸提时间、浸提次数对白头翁皂苷提取的影响。结果:白头翁的最佳醇提工艺为75%乙醇,提取3次,浸提时间3h。结论:本工艺可为提取白头翁生产工艺作参考。
Objective: To optimize the alcohol-extraction process and condition of Radix Pulsatillae. Methods: Alcohol concentration, the extraction time and number of extraction on effect of extraction rate of pulehinenoside B4 were evaluated by orthogonal design L9 (3^4). Results: The optimum condition of the alcohol extraction was: 75% ethanol, 3 times of extraction, 3h for extraction process. Conclusion: The extraction method can be used for reference for the extraction process of Radix Pulsatillae.
