Objective: To optimize microwave extraction technology parameters of Fufang Buwu syrup. Method: Optimization of microwave extraction technology parameters for Fufang Buwu syrup by response surface analysis method. Result: Ratio of material-liquid

extraction time and microwave power had significant impact to yield of psoralen

optimum extraction conditions were as follow:ratio of material-liquid 1∶10

microwave power 40%

extraction time 26 mins. Under this technology

yield of psoralen reached maximum

with estimated value and verified value being of 36.33%

36.38%. Conclusion: This process was simple energy saving and high extraction ratio to old process

and had good reproducible.
