title: [Tocopherol Acetate Reference Standard (Control 021) of National Institute of Health Sciences].
abstract: The raw material of tocopherol acetate was examined for the preparation of the "Tocopherol Acetate Reference Standard (Control 021)", The analytical data obtained were: UV spectrum, lambda max of 278.5 and 284.8 nm and specific absorbance in ethanol at 284 nm = 42.9; IR spectrum, same as that of the Tocopherol Acetate Reference Standard (Control 001); thin-layer chromatography, no impurities were detected until 50 micrograms; high-performance liquid chromatography, total amount of impurities estimated to be less than 0.6%. Based on the above results, the raw material was authorized as the Japanese Pharmacopoeia Tocopherol Acetate Reference Standard (Control 021) of the National Institute of Health Sciences.
