Study on Microwave-assisted Extraction Technology of Rhizoma Chuanxiong

Objective:To determine the optimum microwave-assisted extraction process for Rhizoma Chuanxiong.Method:The process was selected by orthogonal design with the transfer rate of ferulic acid as index.Result:The optimum extraction conditions was as follows:extracting twice with 10 times amount of 40% ethanol for 2 min.The microwave power was 160 W.Conclusion:The optimum extraction process was stable,feasible and could improve extraction efficiency.
