Description	Antioxidant activities of buckwheat seeds, dehulled seeds, hulls, straws and leaves were evaluated and compared with that of oats and barley. Schaall test at 70 oC with gravimetric indication and lard as the substrate was applied. Protection factors expressed as the ratio of induction periods of lard with the tested material addition and lard ranged from 1.3 to 8.0 and raised in the order: buckwheat straws < buckwheat hulls = oats < barley < buckwheat seeds < buckwheat dehulled seeds < buckwheat leaves. Methanol extract of buckwheat seeds showed higher antioxidant activity in comparison with petrolether extract, protection factors amounted to 2.9 and 1.9, resp. Total flavonoid, rutin and tocol contents in tested samples were determined and related to the antioxidant activities. Statistically significant relationship between total flavonoid content as well as rutin content and antioxidant activity of buckwheat material was observed ( R2 = 0.987, p < 0.002, R2 = 0.972, p < 0.002, resp.)
