FIELD: chemistry.
SUBSTANCE: method of identifying alpha-tocopherol involves preparing an alcohol solution of the object being analysed, putting samples of the solution on a chromatographic sheet of the brand "Sorbfil", carrying out chromatography in the presence of the eluent octane - diethyl ether (7:1), developing chromatographic zones of alpha-tocopherol with concentrated nitric acid, and scanning the chromatogram. Processing of the image of the chromatogram obtained is carried out by a computer program "Sorbfil Videodensitometer". The quantitative content of alpha-tocopherol is found from a graduated characteristic curve.
EFFECT: increase in the accuracy and integrity of quantitative determination of alpha-tocopherol due to improvement of quality in chromatographic zones.
