Sunflower (Helianthus annuus L.) is an important oilseeds crop among the four major
oilseeds crop cultivated in the world viz., soybean, brassica, sunflower and groundnut. Two
types of sunflower are grown viz., gil seed purpose and non- oil seed sunflower for
commercial market. Non-oilseed sunflower is known as confectionery sunflower and their
seed generally is larger than that of the oilseed types and has a lower oil percentage with
high protein and sugar content. Vegetable oils are significant sources of antioxidants in
human nutrition. Natural antioxidants present in oils have obtained substantial attention
because of their health and nutritional effects. Plants produce of antioxidant compounds
such as tocopherols and tocotrienols to prevent oxidation of the susceptible substrate.
Antioxidant properties the tocopherols content of oils can give human health benefits like
modulating cancer, cardiovascular diseases and a protective effect by lowering LDL
cholesterol by inhi...biting cholesterol biosynthesis. Over the last few years, increased interest
for natural antioxidant in cold-pressed plant oils has been observed since they have better
nutritive properties in comparation to refined ones. The aim of this study was to investigate
tocopherols composition (a-, B-, y- tocopherols) in selected 10 cold-pressed sunflower oils
obtained from confectionary sunflower hybrids cultivated in Serbia (2017 harvest).
Quantification of tocopherols was carried out using high performance liquid
chromatographyon a column Nucleosil 100-5 NHz with fluorescence detection (Acx=280 nm,
hem=340 nm). The mobile phase was n-hexane/ethyl acetate (70/30, v/v) with a flow rate of
1 ml/min. Total tocopherols content in cold-pressed sunflower oils ranged from 413.13
mg/kg in NS-H-6791 hybrid to 720.99 mg/kg in NS-H-6488 hybrid. Major vitamers for those
tested hybrids was a- tocopherol. The results have shown that there were significant
differences in tocopherols composition and content among the hybrids, indicating the great
genetic potential for improvement.
