中文摘要:

采用蒸馏水作溶剂从南酸枣果实中提取多糖，分别以提取温度、提取时间、料液质量体积比和提取次数为主要影响因素，采用L9（34）正交试验进行提取工艺优化。结果表明，影响南酸枣多糖得率的各因素顺序依次为提取温度、提取时间、料液质量体积比及提取次数，且当提取温度100 ℃，提取时间5 h，料液质量体积比1 g∶40 mL，提取次数1次时，南酸枣多糖的得率最高可达21.79%。

英文摘要:

The polysaccharides fromChoerospondiasaxillaries fruit was extracted by distilled water，and the extraction parameters were optimized using L9（34） orthogonal test with extraction temperature，extraction time，solid-liquid ratio and extraction times as main effect factors. The results indicated that the influence order of them was extraction temperatures，extraction time，solid-liquid ratio and extraction times，respectively. And when the polysaccharides was extracted at 100 ℃ for one time，with a extraction time of 5 h and a solid-liquid ratio of 1∶40（g/mL），the yield of polysaccharides was up to 21.79%.
