Abstract

The oscillatory shaker(extraction) and microwave-assisted extraction methods of alkaloids from F.thunbergii were compared.Furthermore,the optimum extracting conditions of microwave-assisted method were confirmed by single factor analysis and orthogonal test.The results showed that the best conditions for ultrasonic-assisted extraction were as follows: 80% ethanol as the solvent,solid to solvent ratio at 1∶30(m∶V,g∶mL),extraction time 150s,and microwave power 338W.Under these conditions,the extraction rate of alkaloid was 0.011 7%.
