Abstract: PURPOSE: A novel pectin polysaccharides(Angellan-I, Angellan-II) separated from Angelica gigas Nakai is provided, which contains galacturonic acid, arabinose and galactose, therefore shows immune-increasing effect and also can be used as an immune-increasing reagent in the basic study for immunology. CONSTITUTION: A process for the separation of novel pectin polysaccharides(Angellan-I, Angellan-II) from Angelica gigas Nakai comprises the steps of: pulverizing Angelica gigas Nakai root into pieces, adding water and extracting while circulating at 100deg.C for 1hr; adding 3times of ethanol to the residual solution, leaving at 4deg.C for 3hrs and centrifuging to get extracted precipitates; dissolving the ethanol extract in water to remove impurities, adding 3times of ethanol to the residual solution again, centrifuging and processing dialysis; freeze-drying the reagent to get crude polysaccharides; and separating the crude polysaccharides into acidic polysaccharides(Angellan I) and neutral polysaccharides(Angellan II) by dissolving, washing, centrifuging, doing dialysis and freeze-drying.
Abstract translation: 目的：提供从当归纳西分离的新型果胶多糖（Angellan-I，Angellan-II），其含有半乳糖醛酸，阿拉伯糖和半乳糖，因此具有免疫增加作用，并且还可用作免疫增加试剂 免疫学的基础研究。 构成：从当归Nakai中分离出新型果胶多糖（Angellan-I，Angellan-II）的方法，包括以下步骤：将当归Nakai根粉碎成片，加水并在100℃循环提取1小时; 向剩余溶液中加入3倍的乙醇，在4℃下放置3h，离心得到提取的沉淀物; 将乙醇提取液溶解于水中去除杂质，再次向剩余溶液中加入3倍乙醇，离心和加工透析液; 冷冻干燥试剂得到粗多糖; 并通过溶解，洗涤，离心，进行透析和冷冻干燥将粗多糖分离成酸性多糖（Angellan I）和中性多糖（Angellan II）。
