Abstract
The subject handled in this study is the determination of antioxidant activities of extracts obtained from the Urginea maritima (L.) Baker plant's leaves and tubers. Extractions which were obtained using various solvents as methanol, ethanol, acetone and benzine. The antioxidant activity of the extracts was determined using beta-karotene-linoleic acid system. Moreover, the free radical scavenging activity values were tested with DPPH. The concentrations of phenolic compounds in all extracts of UM, expressed as microgram of pyrocatechol equivalents (PEs) were determined with Folin-Ciocalteu reagent (FCR). The results demonstrated that the highest antioxidant activity in the U. maritima (L.) Baker showed in the tubers with ethanol solvent (%72,67) and the lowest in the benzine extract from the tubers (%31,12). The free radical scavenging activity of the methanol extract from the tubers of the U maritima (L.) Baker plant (%66.89) was found lower than the BHT value (%91.12) but still the highest. However, the amount of total phenolic compounds of acetone extract of U. maritime (L.) Baker tubers was 6 times more than ethanol extract. This study demonstrated that U maritime (L.) Baker species have high rate antioxidant capacity.
