First, removing protein by Sevage method. According to literature, it had best efficiency when polysaccharide liquid 2mg·mL~(-1) was treated with chloroform: n-butanol (3:1) and repeated for 3 times. Second, moving pigment with H_2O_2. In order to shorten the time and prevent the broken of structure of polysaccharide, the experiment was operated at 37℃. The following were dialyzation, concentration(60℃) and freeze-drying.

首先Sevage法除蛋白，根据文献，确定氯仿：正丁醇为3：1，多糖浓度2mg·mL~(-1)时，重复三次，除蛋白效果最佳；脱色采用了双氧水氧化法，为加快脱色时间，又要避免双氧水对多糖结构的破坏，实验在37℃下进行；透析、浓缩、干燥过程同样为了保证多糖结构的完整性和提取后物质疏松易溶解，先透析，然后60℃浓缩，最后是冷冻干燥。
