摘　　要：以竹叶为原料,提取其中具有明显抑癌活性的竹叶多糖,整个工艺采用微波辅助技术提取。通过单因素试验与正交试验,研究竹叶多糖提取的最优条件。正交试验结果表明:竹叶多糖以水为提取剂,最佳提取条件是固液比为1∶30,微波作用时间为6min,微波功率为539W,提取4次。在此最佳提取条件下,竹叶粗多糖的得率为0.496%。Bamboo polysaccharide,which has obviously anti-cancer activity,is extracted from bamboo leaves as raw material.With the help of microwave-assisted extraction method,the optimum extracting conditions have been investigated through single-factor experiments combined with orthogonal test.The results show that the optimum extraction conditions：ratio of bamboo leaves to water is 1：30,the power of microwave oven is 539W,6 minutes each time and for 4 times.The yield of bamboo polysaccharide is 0.496% under the optimum conditions.
