摘要
采用反相色谱体系,以蒸发光散射为检测器,ODS分析(?)和异丙醇-乙腈为洗脱剂分离、检测了羊毛脂中甾类化合物和脂肪醇。采用外标法定量分析其中的胆甾醇,平均回收率99.14％,重复性实验的标准偏差(SDE)小于0.01。
Steroids and fatty alcohols in lanolin were separated by inversed liquid phase chromatography using ODS column and acetonitrile/iso-propanol as eluant with evaporation light scattering detector (ELSD). Cholesterol was determined by external standard method, the average recovery is 99.14% and the standard deviation in repeated tests is<0.01.
