摘要: 采用热水浸提、微波和超声波强化提取等3种不同方法提取大枣多糖。结果表明,微波和超声波法提取大枣多糖具有快速、安全、简便、成本低且得到的多糖提取率高,而成分又不被破坏的优点。其中微波辅助提取法的最佳提取率达1.137%,超声波法为0.982%,热水浸提法则为0.889%

Abstract: Several extraction processes were used respectively, such as the traditional hot water extraction method, microwave method and supersonic method, the content of polysaccharide were determined by phenol-sulfuric method to optimize the extraction process of polysaccharide. The optimum conditions of extraction were obtained on the basis of single factor test, it indicates that: the latter two methods are simple, convenient and efficient.
