The raw material for tocopherol was tested for preparation of the "Tocopherol Reference Standard (Control 911)". Analytical data obtained were as follows: infrared spectrum, same as Tocopherol Reference Standard (Control 881); absorptivity, E1%1cm (292nm) = 75.5; thin-layer chromatography, no impurities were detected up to 50.0 micrograms; high performance liquid chromatography (HPLC), four impurities were detected; assay, 100.7% by HPLC. Based on the above results, the raw material was authorized as the Japanese Pharmacopoeia Standard (Control 911).
对生育酚的原料进行了“生育酚对照品（对照 911）”制备的测试。获得的分析数据如下：红外光谱，与生育酚对照品（对照 881）相同；吸光度，E1%1cm(292nm)=75.5；薄层色谱法，在 50.0 微克时未检测到杂质；高效液相色谱法（HPLC），检测到四种杂质；含量测定，通过 HPLC 为 100.7%。基于上述结果，该原料被批准为日本药典标准（对照 911）。
