摘　　要：本文以桑黄子实体为原料,在单因素实验的基础上,运用响应曲面法优化微波辅助提取桑黄多糖的工艺条件.结果表明:对桑黄多糖得率的影响因素按主次排序为:微波功率>液料比>提取时间.确定最佳工艺参数为:微波处理时间5.1min、微波功率540W、提取2次,在此工艺条件下,桑黄多糖得率为4.18%.Based on single-factor studies, response surface optimization was carried out to optimize the extraction process of Phellinus polysaccharides by the microwave-assisted extraction technology. The results showed that polysaccharide yield was most significantly affected by microwave power, extraction time and solid/liquid ratio. The optimal conditions of extraction as follows：extraction time 5.1 min, microwave power 540 W, solid/ liquid ratio 1 ： 41 （w/v）, extraction twice. Under such conditions,the yield of Phellinus linteus polysaccharide could reach 4.18%.
