Extration Technology of Polysaccharide form Hericium Erinaceus

Single factor experiments and orthogonal test packet method combined with the situation were performed to determine the best conditions for polysaccharide form Hericium erinaceus.Effects of extraction temperature,ratio of material to liquid,pH value and extraction time on polysaccharide were investigated.Optimum extraction processing parameter was determined as follows: extraction temperature at 80 ℃,ratio of material to liquid 1 g∶25 mL,pH value at 5.5,extraction time 3 hours.Extraction efficiency of polysaccharide reached 4.5 % by the optimum extraction technology parameters.
