Comparative analysis of fatty acids, tocopherols and phytosterols content in sunflower cultivars (Helianthus annuus) from a three-year multi-local study Phyton
Ayerdi Gotor,A; Berger,M; Labalette,F; Centis,S; Daydé,J; Calmon,A.
Sunflower oil is naturally rich in both unsaturated fatty acids and numerous minor components, with high levels ofa-tocopherol and phytosterols that could play an important role in plant protection. These micronutriments, tocopherols and phytosterols, also exhibit health benefits for humans including reducing both cardiovascular diseases and aging disorders. a−Tocopherol represents more than 95% of total sunflower tocopherol and has the greatest vitaminic activity. Furthermore, this oil contains high amounts of β-sitosterol which is a promising health beneficial phytosterol. The objective of this study was to compare the content and composition of fatty acids, tocopherols and phytosterols in sunflower oil between different cultivars and...

Oleic conversion effect on the tocopherol and phytosterol contents in sunflower oil Phyton
Ayerdi Gotor,A; Berger,M; Labalette,F; Centis,S; Daydé,J; Calmon,A.
In sunflower, conventional breeding is widely used for the modification of traits such as the fatty acid composition, disease resistance, and mainly for obtaining commercial oil with high oleic acid content. There is a growing interest on tocopherols and phytosterols present in sunflower, due to their human health benefits. This emphasizes the need of studies on breeding programs for these bioactive components. A hundred of isogenic pairs of classic and its oleic version of hybrids and parental lines were cultivated in different locations in France between 2003 and 2006. The results indicated that sunflower oil is rich in α-tocopherol and β-sitosterol. However, there was little correlation between traditional linoleic and oleic sunflower...
