Optimization of Microwave-assisted Extraction Process for Icariin from Epimedium by Response Surface Methodology
Objective: To investigate suitability of microwave-assisted extraction technology used in leaf Chinese medicine. Method: Epimedium was taken as example.Three factors were investigated influence of microwave power
solvent-solid ratio
extraction time on yield of extracted for icariin and yield of dry extract by Box-Behnken design.Microwave-assisted Extraction Process for icariin was optimized by response surface design
and compared with traditional extraction technique. Result: Relation fitted quadratic model between yield of extraction for icariin
yield of dry extract and 3 factors investigated.Optimum extraction technology of icariin was:microwave power 800 W
solvent-solid ratio 16
extraction time 37 min.Under these conditions
average yield of icariin was 84.53%
dry extracta sicca was 22.47%. Conclusion: Microwave-assisted extraction of icariin had characteristics of low in time
high extraction ratio
no difference of chemical characteristics peaks and lower energy consumption. Microwave-assisted technology applied to extraction of leafy medicinal materials such as Icariin.
