摘要
目的:优化黄精多糖的水提醇沉工艺。方法:采用正交实验设计,以多糖量为指标,优化黄精多糖水提醇沉工艺。结果:优化水提醇沉提取条件为加水量8∶1,提取1．5 h,提取4次,提取液浓缩后加4倍量无水乙醇沉淀。结论:该优化工艺简便、合理,黄精多糖的提取效率高。
Objective： To select the optimum extraction procedure for polysaccharide from rhizoma polygonati by water extraction and alcohol precipitation （WEAP）. Method： The optimum extraction procedure was selected with the content of rhizoma polygonati by orthogonal test design, Result： The optimum extraction procedure was determined with 8 times of water decocting 1.5h and 4 times, and the polysaccharide was precipitated with 4 times alcohol. Conclusion： The optimum extraction procedure was simple, reliable and the extracting ratio was high.
