Abstract:

Three key factors affecting the extraction yield of Ganoderma lucidum polysaccharides such as ultrasonic power, ultrasonic extraction time and ratio of water to solid were optimized by response surface methodology. Design Expert analysis indicated that the best ultrasonic power, ultrasonic extraction time and the ratio of water to solid were 680 W, 17 min and 28:1, respectively. Under these conditions, the yield of polysaccharide was (20.79 ± 0.11) mg/g, which was consistent with the predicted value.

Key words: Ganoderma lucidum polysaccharides, response surface methodology, ultrasonic extraction
