模拟移动床色谱法分离纯化链甾醇
以羊毛脂中提取的链甾醇为原料,采用模拟移动床色谱法（SMBC）进行了分离纯化。以C18为固定相,甲醇为洗脱液,采用四区SMBC系统,每区有两根色谱柱（150 mm×10 mm×10μm）,经过两次SMBC分离,得到高纯度链甾醇产品。以纯度、生产率和溶剂消耗量为指标,确定链甾醇在SMBC中的最佳分离条件为：切换时间6.4 min,四区流量分别为9.97,7.53,8.53和4.97 mL/min,进料流量1.00 mL/min（第一次SMBC分离）;切换时间6.0 min,四区流量分别为9.95,7.98,8.53和6.62 mL/min,进料流量0.55 mL/min（第二次SMBC分离）。结...

| Notes | Simulated moving bed chromatography; Reversed phase high performance liquid chromatography; Separation and Purification; Desmosterol Separation and purification of crude desmosterol originated from lanolin were conducted with simulated moving bed chromatography（SMBC）.Using C18 as stationary phase,methanol as eluent,four zone SMBC system,two columns in every zone,high purity desmosterol was obtained through twice SMBC separations.The column used was 150 mm×10 mm i.d.,particle size 10 μm.Based on purity,productivity and eluent consumption,the optimal SMBC separation conditions for desmosterol were determined as follows： switch time 6.4 min;flow rate of Q1=9.97 mL/min,Q2=7.53 mL/min,Q3=8.53 mL/min,Q4=4.97 mL/min;QF=1.00 mL/min（first SMBC separation）;switch time 6.0 min;flow rate of Q1=9.95 mL/min,Q2=7.98 mL/min,Q3=8.53 mL/min,Q4=6.62 mL/min;QF=0.55 mL/min（second SMBC separation）.Under above conditions,firstly the impurity with adsorption capacity stronger than desmosterol was removed,and then the impurity with ad |
