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.
