Ganoderma lucidum belongs to wood mushroom which grows on logs of died Erythrophleum fordii. Reishi mushroom is useful for health and have been used for a long time. In the market, reishi mushroom products are sold as fruiting bodies or drying slides. These products are not handy for customers. In this research, Ganoderma lucidum was cultivated in laboratory of Faculty of Biotechnology and Food Technology, Thai Nguyen University of Agriculture and Forestry. The factors to extract polysaccharides had been identified. The polysaccharides concentration in the extraction with ultrasonic waves was 4,26 mg/g in 4 minutes. The suitable concentration of ethanol for extraction was 80% with 4,81 mg/g polysaccharides. Ratio of material and solution was 1/20 (g/ml) with polysaccharides concentration as 4,98 mg/g; In extraction, polysaccharide concentration showed the result as 5,32 mg/g in 90 minutes and 5,83 mg/g at 80oC.
