Edible vegetable oils were analysed for tocopherols by reversed-phase HPLC. These included refined corn, soybean, sunflower, rapeseed, grapeseed, and peanut oils, and cold-pressed extra-virgin olive, linseed, rapeseed, and sunflower oils. Total measured tocopherol concentrations varied in the range from 121 to 829 mg/kg. The contents of individual α-, (β+γ)-, and δ-tocopherols show a great diversity depending on the kind of oil. Moreover, the effect of photooxidation on the tocopherol content was studied in cold-pressed sunflower and rapeseed oils. These studies revealed only a minor decomposition of tocopherols under visible light.

PL

W pracy przedstawiono wyniki oznaczeń tokoferoli, metodą HPLC w odwróconym układzie faz, w olejach roślinnych, w tym w olejach rafinowanych (kukurydzianym, sojowym, słonecznikowym, rzepakowym, z pestek winogron, arachidowym) oraz tłoczonych na zimno (oliwie z oliwek, lnianym, rzepakowym i słonecznikowym). Wyznaczona całkowita zawartość tokoferoli (w zakresie 121 do 829 mg/kg) oraz zawartość poszczególnych związków z tej grupy (α-, (β+γ)-, i δ-tokoferoli) znacząco zależy od rodzaju oleju. Badania olejów tłoczonych na zimno słonecznikowego i rzepakowego naświetlanych promieniowaniem z zakresu widzialnego wykazały niewielki wpływ procesu fotoutleniania na zawartość tokoferoli.
