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

    Yildirim, Nuran Cikcikoglu; Paksoy, Mehmet Yavuz; Yildirim, Numan; Yuce, Ebru

    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.

    COMPARATIVE ANATOMY OF STEM AND LEAF OF RICOTIA L. GROWING IN TURKEY

    Selvi, Selami; Paksoy, Mehmet Yavuz

    The present paper deals with a comparative anatomy of stem and leaf of Ricotia species growing in Turkey. In addition, stomatal index and rate of these species were calculated. A diagnostic key based on combined stem, leaf and leaf epidermal characteristics were presented. The presence or absence of trichome, cortex parenchyma layer, sclerenchyma, mesophyll structure and epidermal surface were found to be important characters for the identification of Ricotia species.
