Optimization of Ultrasonic-assisted Extraction for Polysaccharides from Ganoderma lucidum

The ultrasonic-assisted extraction conditions of polysaccharides from Ganoderma lucidum were optimized through single factor experiments and orthogonal regression combination design. The results showed that under the optimum conditions such as solid-liquid ratio of 1∶35(g/mL), ultrasonic power of 80 W, extracting 35 minutes under 50 ℃, the extraction yield of polysaccharides from Ganoderma Lucidum was 2.06%.
