COMPARATIVE ANTIOXIDANT ACTIVITY IN SEEDS OF IRRIGATED AND NON-IRRIGATED FLAX CULTIVAR ALEXIN

What is it about?

Flax from cultivar Alexin was grown on three different water regimes: non-irrigated, halfdose and full-dose irrigated. Seeds were harvested, extracted in 70% ethanol solutionand analyzed for antioxidant activity, using the DPPH method. Results show an extreme variation of antioxidant activity with irrigation regime, from just 3.18% in non-irrigated flax, to 48.24% in full-dose irrigated one, with 18.08% at halfdose irrigation, corresponding to IC50 values of 45.68–106.88.Irrigation, even with half dose raised linseed tissue extract potential to strongly antioxidantand to very strongly antioxidant at full dose..These results can be linked to data showing a major increase in concentrations of some key compounds, especially of phenolic compounds
