摘要
[目的]探讨不同提取方法对黄芩苷提取率的影响.[方法]采用超高压处理,通过不同的提取压力、料液比、压力作用时间和乙醇浓度测定超高压条件下黄芩苷提取率,并与浸提法、煎煮法、回流法和微波法等传统的黄芩苷提取工艺进行比较.[结果]当提取压力为450 MPa、乙醇浓度为40%、压力作用时间为25 min、料液比为1∶10时,黄芩苷提取效果达到最佳.[结论]超高压条件下,黄芩苷的提取率明显高于其他几种传统提取方法,这为利用超高压研究黄芩苷的提取提供了依据.
Abstract
[Objective] The research aimed to discuss the effects of different extraction methods on the extraction rate of baicalin.[Method]The extraction rate of baicalin under ultra high pressure was determined by different extraction pressure, solid-liquid, pressure action time and ethanol concentration,and compared with the traditional extraction process of baicalin such as solvent extraction,decocting method,reflux method and microwave method.[Result]When the pressure was 450 MPa, the ethanol concentration was 40%, the pressure action time was 25 min and solid-liquid ratio was 1∶10, the extraction effect of baicalin was the best.[Conclusion] Under ultra high pressure, the extraction rate of baicalin is significantly higher than that of other extraction methods.It also provides the basis for the study on the extraction rate of baicalin by the method of ultra high pressure.
