[Tocopherol Reference Standard (Control 881) of National Institute of Hygienic Sciences].
Tocopherol was tested for the preparation of "Tocopherol Reference Standard (Control 881)". Analytical data obtained were as follows: infrared spectrum, same as Tocopherol Reference Standard (Control 851); absorbance, E1%1cm (292 nm) = 73.7; thin-layer chromatography, contaminants were not detected until 12.5 micrograms; high-performance liquid chromatography, six contaminants were detected; assay, 100.4%. On the basis of those results, this material was authorized as the Japanese Pharmacopoeia Standard (Control 881).
