摘要： Clitocybe maxima (Gartn. ex Mey.: Fr.) Quel. is a favorable edible mushroom. As a bio-waste (or defined as byproduct), it produces a high proportion of biomass in mushroom stipe for about 45% of entire fruits. To increase its value added utilization, three extraction methods (as hot water, microwaveassisted and complex-enzyme-hydro lysis-assist) were conducted. The extraction effect on the polysaccharide of Clitocybe maxima stipe was compared and the processing conditions in extraction were optimized. The content of Clitocybe maxima polysaccharide was determined with Phenol Sulfuric Acid Method. The yield and purity of the stipe polysaccharide obtained with three extractions were greatly different, which were 5.86% and 40.23% for hot water extraction, 9.4% and 52.62% for microwareassist extraction, 10.26% and 53.13% for complexenzyme-hydrolysis extraction, respectively. Results indicated that the complex-enzyme-hydrolysis-assist extraction was the best approach for extracting the polysaccharide from Clitocybe maxima stipe with the advantages in high extraction efficiency, energy saving and running time saving.
