Phytochemical study of biological active substances in the component of seed and flaxseed oil Linum usitatissimum L

Abstract

Flax seeds and oil have an increased interest due to the high content of antioxidant compounds, lignans-polyphenols, dietary fiber, oil and essential unsaturated fatty acids omega-3, omega-6, omega-9.  Due to biologically active substances and nutrients from flax seeds, they have become important ingredients for the realization of foods used in the human diet and as functional food in medicine [1-3]. The research was focused on examining the variability of the composition of three varieties of flax seeds collected from plants grown in the Republic of Moldova, Ukraine, Romania; optimization of the extraction system, analysis of extract from defatted seeds and assessment of polyphenol content, appreciation of the quality of flax oils extracted from different varieties of seeds, according to the organoleptic and physico-chemical parameters
