Extraction method for flammukinan

The invention relates to the technical field of flammukinan and in particular relates to an extraction method for flammukinan. The extraction method comprises the steps of performing superfine grinding; adding water into ultrafine powder, adding cellulose for enzymolysis, and then adding pectinase and xylanase for enzymolysis; performing ultrasonic extraction; and performing concentration, alcohol precipitation, deproteinization, decoloration, dialysis and drying to obtain the flammukinan. The flammukinan is extracted through ultrafine grinding and enzymolysis combined ultrasonic extraction, so that the extraction efficiency is obviously improved, and the time is short; raw materials and energy are saved, and the activity of the flammukinan is kept; moreover, during enzymolysis by the compound enzyme, the cellulose, the pectinase and the xylanase are added in sequence, so that the extraction efficiency is improved when being compared with the extraction efficiency when the three enzymes are independently or jointly added. The invention provides the high-efficiency extraction method for the flammukinan.
