Changes in the Content of Phenolic Compounds
At full maturity, the content of phenolic compounds in three varieties ranged from 0.26 to 0.36 mg of analyte/kg of flaxseed oil. The highest content of total phenolic compounds using the Folin–Ciocalteu method was detected in P129 variety (196.42 mg CAEs/kg of flaxseed oil) at 7 DAF. Results of this study indicate that flaxseed oils contain

Abstract The phenolic fraction of flaxseed oil was quantified during the development of three varieties (H52, O116 and P129). Seed samples were collected at regular intervals from 7 to 56 days afte...
Flaxseed contains also other phenolic compounds, such as phenolic acids. Considering the importance of the phenolic fraction of flaxseed, high performance analytical methods have been developed to characterize its complex phenolic pattern. The understanding of the nature of these compounds is crucial for their possible exploitation in drugs and functional foods. (Authors abstract)
Changes Occurring in the Volatile Constituents of Flaxseed
Flaxseeds contain functional components such as dietary fiber, oil, protein, and phenolic compounds, which are associated with a number of health benefits. 1, 2 Notably, flaxseed oil has a comparably high content of alpha‐linolenic acid (ALA), which is a precursor of long chain (O‐3) fatty acids such as eicosapentaenoic (EPA) and
phenolic compounds, such as phenolic acids. The understanding of the nature of these compounds is crucial for their possible exploitation in drugs and functional foods. Until the mid 1990’s, the number of methods available for analysis of lignans and other compounds in flaxseed was limited and were divergent in terms of yields. Moreover, the
