The raw material of tocopherol acetate was examined for the preparation of the "Tocopherol Acetate Reference Standard (Control 971)". Analytical data obtained were as follows: infrared spectrum, the same as that of the Tocopherol Acetate Reference Standard (Control 941); specific absorbance, E1 cm 1% (284 nm) = 43.0; thin-layer chromatography, no impurities were detected until 50.0 micrograms of the loaded raw material; high-performance liquid chromatography (HPLC), one impurity was detected and the amount was estimated to be about 0.68%; assay by HPLC, 100.2%. Based on the above results, the raw material was authorized as the Tocopherol Acetate Reference Standard (Control 971) of National Institute of Health Sciences.
