摘要
采用热水提取法提取大枣多糖,并对提取工艺及料液比、温度和时间因素对提取的影响进行研究,通过正交试验优化最佳提取工艺。最终确定最佳提取工艺为:料液比1∶15,温度60℃,时间3 h。
The optimal condition of extraction for polysaccharides from Ziziphus jujube Mill. is studied in this paper. The effects of the factors such as extraction time, extraction temperature and the material-water ratio on the extraction of polysaccharides are studied using hot-water extraction method. Through the orthogonal test, the optimum conditions for extracting polysaccharides from Ziziphus jujube Mill. are obtained as follows, the material-water ratio being 1 ： 15, extraction temperature being 60 ℃, and extraction time being 3 h.
