In order to provide the basic data for the developing and utilization of the bulbil, the extraction process of polysaccharide from bulbil was studied using combined enzymes. The forecasting model was set up with the orthogonal experimental method on the basis of single-factor experiments. The optimum extraction parameters were as follows: 2% celluose enzyme plus 1.5% pectinase and 2% acid protease at reaction temperature 40℃ and pH 5.5 for 3 h. With the optimal conditions, the extraction rate of polysaccharide was 15.80%.
