摘要
目的：研究超滤膜技术应用于提纯灵芝多糖的可行性及工艺。方法：采用卷式超滤膜对灵芝多糖进行分离提纯研究。结果：膜截留分子量6000D、超滤温度45～50℃、超滤压力0．6MPa、时间45min，制得灵芝多糖的纯度为73．5％，回收率为69．4％。结论：超滤膜技术分离提纯灵芝多糖工艺简单，效果较好，有产业化前景。
Objective： To investigate the feasibility and technology for purifying Ganoderma lucidum polysaccharide （GLP） by ultrafihration. Methods： A spire roll uhrafiltration unit was selected to purify GLP. Results： Purity of 73. 5% and recovery ratio of 69.4% for GLP were obtained by using a membrane with cut-off molecular mass of 6000, while operating temperature, pressure and time were 45 - 50℃, 0. 6 MPa and 45 min, respectively. Conclusion： Ultrafiltration is one of the new feasible methods for the purification of GLP.
