采用高效液相色谱法 ( C18柱 )测定维生素 E胶丸中维生素 E含量 ,以甲醇 -氯仿 ( 85∶ 1 5 )为流动相 ,检测波长为 2 84 nm,维生素 E浓度在 3.66mg/ ml～ 36.60 mg/ ml范围与峰高线性关系良好 ( r=0 .9999) ,平均回收率为 98.7% ( RSD % =0 .4 1 % )。
The content of vitamin E in vitamin E capsules was determined by high performance liquid chromatography (C18 column). The mobile phase consisted of methanol and chloroform (85:15), the detection wavelength was 2 84 nm and the concentration of vitamin E was 3.66 mg / ml ~ The linear range of 36.60 mg / ml was linear with peak height (r = 0.9999). The average recovery was 98.7% (RSD% = 0.41%).
