摘要
利用密闭微波样品制备系统(具有压力控制部件),对当归中的有效成分阿魏酸的萃取进行研究,比较了密闭微波萃取同超声波萃取和索氏萃取阿魏酸提取率的差异.结果表明:微波萃取与其他两种萃取方法相比,具有速度快和萃取率高的特点.并得到了阿魏酸提取的最佳条件:微波功率为400 W,萃取剂为90%的乙醇(体积分数),固-液比为1∶15,微波辐射为240 s,当归粒径为75μm.
Microwave-assisted extraction of ferulic acid from angelica sinensis was studied by an obturated microwave-assisted extraction device with a pressure controling part. In the same time,it was compared with ultrasonic extraction and soxhlet extraction. It was found that, the microwave-assisted extraction lead to a higher extraction ratio with short time, and hiqhest extration ratio can be reached by the best extraction conditions.
