【摘要】 通过单因素实验对影响碱提灵芝菌丝体多糖的各种因素进行了研究,确定提取条件为:提取温度65℃,提取时间4h,碱料(体积:质量)比4:1,碱液浓度0.5mol/L.在此条件下提取并对所得水溶性多糖的抗氧化作用进行了初步研究,表明其对羟自由基有较好的清除能力,在一定范围内清除率与糖的质量浓度呈正相关.更多还原

【Abstract】 The factors influencing on alkaline extraction of polysaccharides from the mycelia of Ganoderma lucidun was studied. The optimum conditions were: extractoin temperature: 65℃, extraction time 4 hr,the ratio of material to NaOH 1 : 4, the concentration of NaOH 0. 5 mol/ L. The alkaline extracted product, water soluble polysaccharides, exhibited obvious scavenging effects for hydroxyl free radicals (HFR) and had positive correlation with initial sugar concentration.更多还原
