摘要
探索了超滤法分离纯化刺参酸性粘多糖的工艺。确定分离纯化条件为:采用截留分子量8 kDa的超滤膜,压力为0.3 MPa,温度为10℃。此工艺制得多糖纯度为93.4%、收率为0.32%,多糖截留率达到97.2%。
The separation and purification technology of acidic mucoplysaccharide from Stichopus japonicus by ultrafiltration was investigated. The ultrafiltration was determined to carry out at pressure of 0.3 MPa and temperature of 10℃ with retention molecular weight of 8 kDa for membrane. The mucopolysaccharide with purity of 93.4% ,yield of 0. 32% and retention rate of 97.2% was obtained in the process.
