摘    要:目的 微波提取黄芩中黄芩苷的研究。方法 应用国产具有压力控制附件的MSP-100D专用微波制样系统,进行黄芩中有效成分黄芩苷的微波提取研究。微波提取的溶剂选择、加热的溶剂压力和微波辐射时间,用正交实验设计进行了考察。结果 通过对实验结果的分析。综合经济因素和实验过程的方便性。在70%微波功率(微波炉的最大功率850瓦)下,微波最佳提取条件为35%乙醇作溶剂,溶剂倍量30,提取压力0.15MPa、恒压时间30s即可获得好的黄芩苷提取率。结论 微波法提取不仅所需时间短,平行性好,而且提取率比超声波法高近10%。

关 键 词:微波提取  正交实验  黄芩  黄芩苷  中药

Abstract:Object To study the microwave assisted procedure for the extraction of baicalin from root of Scutellariae baicalensis Georgi Methods An MSP 100D domestically made microwave sample preparation system with a maximum power of 850 watts was used. The effects of solvents, pressure/temperature of solvents and microwave radiation time on the yield of baicalin were studied by orthogonal experimental design. Results The optimal experimental conditions were extraction at 70% of microwave power with 30 times of 35% ethanol at a constant heating pressure/temperature of 0.15 MPa for 30 s. Conclusion The microwave assisted extraction not only takes a shorter time with better parallel results, but also gave an increased yield of about 10% as compared with ultrasonic extraction.
Keywords:microwave  assisted extraction  orthogonal test  root of Scutellariae baicalensis Georgi  baicalin
