| 摘 要： | 应用超声波技术对北五味子多糖进行提取，并对北五味子多糖的抗油脂氧化性能进行研究。结果表明，超声波提取的最佳工艺条件为：以60％的乙醇作为溶剂，超声波功率400w，固液比为1：25，提取温度55℃，提取时间40min，北五味子多糖的提取率可达到22．30％，超声波法提取比传统法的提取率高出36．58％。通过红外光谱分析，超声波浸提没有使北五味子多糖的结构发生改变。北五味子多糖对油脂具有较强的抗氧化性能，抗坏血酸对北五味子多糖具有协同抗氧化作用。

| Abstract: | The polysaccharides extracted from fruit of Schisandra chinensis(Turcz.) Baill.and its antioxygenic property to grease were studied by the ultrasonic wave technique.Results indicated that the optimal extraction condition were obtained as ultrasonic power 400W,solid to liquid ratio 1:25(g:mL),extraction temperature 55 degrees C,and extraction time 40minutes,using 60% ethanol as solvent.The yield of polysaccharides from S.chinensis could reach 22.3% under the optimal extraction condition,and the extraction ra... |
