蒙药查干-扫日劳中香豆素类成分的提取工艺研究

摘要

利用超声波法辅助提取蒙药查干-扫日劳（Chagan-sorlo）中香豆素类成分，确定其最佳提取工艺，为有效提取香豆素类成分提供参考和生产指导。在不同提取条件下，利用超声波法进行提取、测定和分析蒙药查干-扫日劳的香豆素类主要成分（佛手柑内酯与花椒毒素）。当溶剂体积分数为70％，提取时间为20 min ，超声波功率为175 W ，温度为25℃，固液比为1∶20，用80～100目进行提取时，上述两种香豆素类成分的提取率最优。%The present paper discusses ultrasonic extraction method aided extraction of coumarin from a Mongolian drug , Chagan-sorlo (Radix Glehniae) ,aiming to study out how much coumarin contained in Chagan-sorlo ,and to provide the scientific basis and production guidance for extracting coumarin from Chagan-sorlo .Under different conditions the coumarin in Chagan-sorlo was extracted by ultrasonic ,measured and analyzed ,and then HPLC was used to carry out the measurement .Result showed that with solvent volume fraction of 70% ,extraction time of 20 min ,ultrasonic power of 175 W ,temperature of 25 ℃ , solid-liquid ratio of 1∶20 ,and 80~100 mesh extraction ,the coumarin extraction reaches the highest yield .
