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

Öz

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.

Dört farklı genotipe sahip keten (Linum usitatissimum L.) tohumlarının biyokimyasal karakterizasyonu

Öz

Keten (Linum usitatissimum L.) tohumları, endüstri ve doğal sağlık ürünleri alanında kullanılan yağlı tohumlardır. Biyolojik olarak aktif pek çok fitokimyasal ve antioksidan özelliklere sahip maddeyi yapılarında bulundurabilirler. Bu çalışma, dört farklı genotipteki keten tohumlarının (Avangard, Bony Doon, Linda ve Linton) biyoaktif içeriklerinin araştırılmasını ve özetlenmesini hedeflemiştir. Buna nedenle oksidan ve antioksidan parametrelerinin (fenolikler, flavonoidler, β-karoten, likopen, DPPH radikal yakalama aktivitesi, MDA, prolin, SOD, CAT, APx ve GR) dört farklı keten tohumundaki biyokimyasal çeşitliliği araştırılmıştır. Sonuçlara göre Linda türü keten tohumlarının diğer çeşitlere oranla beklenmedik bir şekilde farklı fitokimyasal ve antioksidan profiline sahip olduğu, bu tohumların oksidatif durumlarının oksidan molekülleri üretmeye eğilimli olduğu DPPH radikal yakalama, MDA ve antioksidan enzim aktivite sonuçlarına göre belirlenmiştir. Ayrıca diğer keten tohumlarının fark edilebilir şekilde yüksek oranda antioksidan ve fitokimyasal potansiyele sahip oldukları gösterilmiştir. Bu nedenle terapötik olarak önemli özellikleri ve antioksidan içerik açısından zengin olmaları nedeniyle keten tohumlarından daha fazla faydalanılmalıdır.
