Objective： This study aim to investigate the microwave extraction technology in the application of exocarpium cirri grandisthis polysaccharide extraction. Methods： Analyze the influence of process paramaters liquid to solid ratio,microwave power, microwave temperature, microwave time on the yield of exocarpium cirri grandis polysaccharide. Based on the response surface analysis with the Design-Expert software program, the extraction condition of the microwave for exocarpium citri grandis polysaccharides was optimized. Results： The Optimal microwave extraction conditions were： liquid to solid ratio was 70, microwave power was 546.56 W, microwave temperature was 100 ℃, microwave time was 22.32 rain. Under these conditions, the exocarpium citri grandisthis polysaccharides yield can reach 24.64%. Conclusion： Microwave extraction technology is suitable in the extraction of exocarpium citri grandisthis polysaccharides. The statistical model is highly reliable. The results of this study have great significance on the research of microwave extrac- tion polysaccharides technology.
