SCREENING OF TOTAL ANTIOXIDANT STATUS OF RICOTTA L. AND SOME GRAMMOSCIADIUM DC SPECIES FROM TURKEY

This study was aimed at screening the total antioxidant status (TAS) of genus Ricotta L. and some Grammosciadium L. from Turkey in order to find new potential sources of natural antioxidants. The TAS level of a total of 12 plant extracts from non-edible plant materials was examined. According to the results, hexanic extract of R. sinuata plant exhibited the lowest antioxidant status (2.41 mmol Trolox equivalent/l). The highest TAS level was determined in ethanolic extract of the G. daucoides (4.36 mmol Trolox equivalent/l). As a result, due to its antioxidative properties, ethanolic extract of G. daucoides can be utilized as a natural source of antioxidants.
