Biochemical characterization of four different genotypes of Flax (Linum usitatissimum L.) seeds

Flaxseed ( Linum usitatissimum L.) is an oilseed used in industrial and natural health products. It accumulates many biologically active compounds having strong phytochemicals and antioxidant properties. This study aims to provide an entire portfolio of bioactive compounds present in four different genotypes of flaxseed ( Avangard, Bony Doon, Linda and Linton). Biochemical diversity among these four different types of seed with respect to oxidant and antioxidant parameters (phenolics, flavonoids, β-karoten, lycopen, DPPH scavenging activity, MDA, proline, SOD, CAT, APx and GR) were investigated. According to results, Linda types are found to have unusual phytochemicals and antioxidant profile since its oxidative status tends to the production of oxidant molecules which was reflected in differences in radical scavenging, MDA and antioxidant enzyme systems. Other flaxseeds demonstrate noticeable activities with their antioxidant potential together with their high phytochemicals. Therefore, they may be utilized as a promising source of therapeutics since they might provide an appropriate source of antioxidants.
