Phenolic compounds are very important plant constituents because they exhibit antioxidant activity by inactivating free radicals or preventing decomposition of hydroperoxides into free radicals. In our previous work, the total phenolic content in winter savory was determined by the Folin Ciocalteu method (expressed as a chlorogenic acid equivalent per g dry weight of plant), while phenolic compounds were identified and quantified by the HPLC method [14]. The results obtained by the Folin Int. J. Mol. Sci. 2007, 8 1015 Ciocalteu method showed that the quantity of phenolic compounds in ethyl acetate (969.43 µg/g) and n-butanol (1358.14 µg/g) extracts were significantly higher
