摘　　要：[目的]优化热水浸提猴头菌多糖的工艺参数。[方法]采用热水浸提法对猴头菌中的多糖进行提取,对影响浸提效果的浸提温度、浸提时间、料液比、浸提次数等因素进行了研究。[结果]试验表明,猴头菌多糖提取的最佳工艺参数为:料液比1∶15 g/ml,浸提温度80℃,浸提时间2 h,浸提次数2次,乙醇沉淀多糖的终浓度为75%,此条件下猴头菌多糖的提取率可达8.87%。[结论]研究可为猴头菌及其他菌类热水浸提多糖提供参考。[Objective]To optimize technique parameters of extracting polysaccharides from Hericium erinaceus by hot water extraction. [Method]The main influencing factors for extraction,such as temperature,time,solid-liquid ratio,times were studied. [Result]The results showed that the optimal parameters to extract polysaccharides in Hericium erinaceus were as follows： the ratio of solid to liquid 1∶ 15 g / ml,extraction at 80 ℃ for 2 h,with twice extraction,75% ethanol concentration for polysaccharide precipitation. In this condition,the extraction rate of polysaccharide could reach 8. 87%. [Conclusion]The study can provide reference for extracting polysaccharides from Hericium erinaceus and other bacteria by hot water extraction.
