Pleurotus citrinopileatus polysaccharides ware extracted from fermentation liquid by acetone under the conditions of different solvent concentration, extracting duration and temperature. The optimal design of extraction was analysed by using orthogonal test. The results showed that under the condition of acetone concentration of 75%, extraction duration of 1.5h, and temperature of 70℃, the highest yield of Pleurotus citrinopileatus polysaccharides was obtained. 相似文献
