摘  要:
Objective:The process conditions were optimized to provide a feasible,economic and effective method which could improve the extraction yeild of total flavones from Huai jiao.Methods:A new enzymatic extraction process of total flavonoids from huai jiao was used,and the process conditions were optimized by response surface methodology(RSM).Results:The optimum extraction parameters were as follows:pectinase/sample ratio,5.5g/kg,solvent/sample ratio,25:1,at 59℃ extraction 1h,the average extraction rate was 3.121 mg/g,which increased 75% compared with traditional ethylalcohol processes.Conclusion:Enzymatic extraction was highly efficient and little pollution,which could provide reference for its future industrial production.
