Leaves and flowering tops of thyme (Thymus vulgaris L.) were extracted with ethyl alcohol and supercritical carbon dioxide. Antioxidant activity was measured in sunflower oil at 0.3, 0.6 and 1% concentrations of extracts by oven test and Rancimat method. The activities of extracts were compared to those of butylated hydroxytoluene at 0.01 and 0.1% level. The ethanolic extract showed a slightly higher antioxidative effect than that obtained by supercritical fluid extraction. The effectiveness of both extracts added at 0.6% level were equal to that of 0.1% of butylated hydroxytoluene.
