The enzymatic hydrolysis conditions for the extraction of dioscin by compound enzymatic method were studied, and the extraction effects of compound enzymatic method, cellulase method, amylase method and glycated enzyme method were compared. The experimental results showed that the cellulase method had the highest purity. The compound enzymatic product has the highest yield, and has the characteristics of short time and low temperature in terms of enzymatic hydrolysis conditions. Finally, the compound enzymatic method was determined as the best method, and the optimal enzymatic hydrolysis conditions for extracting diosca saponin were as follows: enzymatic hydrolysis time was 16 h, enzymatic hydrolysis temperature was 35°C, enzymatic hydrolysis PH value was 5.0, and the enzyme amount per gram of yellow turmeric was 0.04g.
