Abstract:
The application of ultrasonic to polysaccharide extraction from Termitomyces albuminosus was investigated. And the best ratio of water to Termitomyces albuminosus, ultrasonic power, ultrasonic time, water temperature, extraction time and ethanol concentration were 10 times, 100 W, 10min, 80 ℃, 120 min and 90%, respectively. Under those conditions, the yield of crude polysaccharide reached 19.78%, which was higher than that without ultrasonic pretreatment. The content of purified polysaccharide by Sevage reached 87.23%.
