摘　　要：通过响应面分析（ＲＳＡ）法，优化了灵芝菌丝体胞内多糖的热浸提条件，提取温度为９５℃，时间为３．５ ｈ，湿菌体与水的量比值为１∶２．５，此时胞内多糖提取率达到最大值，为１０．５ｇ／ｋｇ．The extraction process of intra-polysaccharides from mycelia of Ganoderma lucidum was optimized by the method of response surface analysis (RAS).The maximum yields of polysaccharides were up to 10.5 g/kg dry mycelia under the following conditions: extractim temperature 95 ℃;extraction time 3.5 h;mycelia/distilled water 1∶2.5.
