摘要：目的:通过微滤和超滤分离纯化大黄多糖。方法:采用微滤结合不同截留相对分子量的管式超滤膜串联工艺。结果:实验确定的最佳工艺条件为:超滤时间控制在80 min左右,温度35～40℃,操作压力0.08～0.12 MPa,pH 6～8,料液多糖浓度为原始提取液浓度的0.5倍,多糖回收率可达到53.7%,浓度可提高到进料液的2.73倍。结论:该工艺简单可行,可用于纯化大黄多糖。
Objective:To purify Rhubarb polysaccharides via micro-filtration and ultra-filtration.Method:The technology adopted micro-filtration and tubular membrane with different cut-offmolecular weights.Result:Experiment results showed that the optimum operating conditions were that the ultra-filtration time controlled around 80 min,the temperature was set the 35～40℃,the operating pressure was 0.08～0.12 MPa,the pH was 6～8,and a sample that of polysaccharide was 0.5 times of original concentration. The recovery ratio...
