Beschreibung
Zusammenfassung:	According to the wine-processed polygonatum sibiricum polysaccharide extract and the preparation method thereof, wine-processed polygonatum sibiricum polysaccharides with different molecular weights and polarities can be separated and purified through step-by-step alcohol precipitation, 70% polygonatum sibiricum water-soluble polysaccharide alcohol precipitation components are obtained, and the components are simple in monosaccharide composition, high in sugar content, low in protein content, high in galactose proportion and high in immunocompetence. The preparation method disclosed by the invention has the advantages of simplicity and convenience in operation and low cost, is an effective method for separating and purifying the polygonatum sibiricum polysaccharide, and has a wide application prospect. 本发明提供一种酒制黄精多糖提取物及其制备方法，本发明采用"分步醇沉"可将不同分子量、极性的酒制黄精多糖进行分离、纯化，得到70%黄精水溶性多糖醇沉组分，该组分中单糖组成简单，糖含量高，蛋白含量低，半乳糖比例升高，免疫活性强。本发明制备方法具有操作简便、成本低的优点，是一种有效的分离纯化黄精多糖的方法，具有广阔的应用前景。
