The present study was carried out on the antioxidative activities of ethanol, 70 % ethanol, acetone, 70 % acetone, water, ethyl acetate, and hexane extracts of evening primrose (EP) meals and rapeseed (RS) meals. The extracts were characterised by a number of phenolic compounds. The antioxidative activities of extracts were studied on Oxidograph apparatus at 110 deg C. Rapeseed oil was used as a substrate. As for the observed experimental results we can state that the ethanol and 70 % acetone extracts contained the largest amount of phenolic compounds, but the strongest antioxidative activity was found out in the case of ethyl acetate extract of EP meals and ethanol extract of RS meals.
