title: [Tocopherol Acetate Reference Standard (Control 001) 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 001)". Analytical data obtained were: IR spectrum, same as that of the Tocopherol Acetate Reference Standard (Control 974); specific absorbance, E/cm% (284 nm) = 43.7; thin-layer chromatography, no impurities were detected until 50 micrograms of the loaded raw material; high-performance liquid chromatography (HPLC), total amount of impurities estimated to be less than 0.6%; assay by HPLC, 101.7%. Based on the above results, the raw material was authorized as the Japanese Pharmacopoeia Reference Standard (Control 001).
