摘　　要：以鹿茸为原料,比较不同生长阶段鹿茸多糖含量的差异性,并对其提取条件进行优化。采用超声波辅助提取法提取鹿茸多糖,并用Box-Behnken中心组合实验设计优化提取条件。实验结果表明:不同生长阶段的鹿茸中二杠茸多糖含量为12.47mg/g,高于毛桃和三杈茸(P<0.05);优化的提取条件为pH=9.2、超声时间22min、超声功率500W、液料比48:1,在此条件下二杠鹿茸中多糖得率为0.98%。Selecting velvet antlers as the raw materials,the content of polysaccharide at different growth stages were compared and the extraction conditions of polysaccharide were also optimized.Ultrasonic wave assisted was used to extract polysaccharide, Box-Behnken experiment was also designed to optimize the extraction conditions. Results showed that content of polysaccharide in two branched was 12.47mg/g, which was higher than three branched （ P 〈 0.05）.pH of 9.2, ultrasonic time of 22min, ultrasonic power of 500W, liquid-solid ratio of 48： ] were the optimal conditions.Under such conditions,yield of polysaccharide in two-branched was 0.98%.
