The first thorough arrangement of the genus Scorzonera was given by DE CANDOLLE (1805). According to his system Scorzonera unites perennial herbs and shrubs with simple, entire, rarely pinnatifid leaves, phyllaries always deprived of horns, seeds mainly without or with hollow pedicels. Considerable changes in the treatment of the genus Scorzonera were introduced by BOISSIER (1875) who included Podospermum DC. and Epilasia (BUNGE) BENTH. as sections within the genus Scorzonera. The most complete and much changed system was given by LIPSCHIZ in two parts of this classical “Fragmente monographiae Scorzonera” (1935, 1939). The concept of the genus introduced by Lipschiz was accepted by many regional “Floras” (CHAMBERLAIN, 1975; CHATER, 1976; RECHINGER, 1977). According to CHATER (1976) the genus Scorzonera is represented by 28 specie...

The sequence data of the nuclear ITS and of two chloroplast regions, trnL-trnF spacer and rbcL gene, obtained from thirteen Globularia L. taxa, including five Anatolian endemics, representing six sections altogether, were analyzed in order to determine the relations between the European and the Anatolian species and get a better insight into the phylogeny of several closely related Globularia taxa. Materials and Methods: Total cellular DNA was extracted from fresh or frozen leaf tissue of thirteen Globularia samples. The ITS regions of nuclear DNA and two chloroplast DNA regions were amplified and sequenced. Obtained nuclear and combined plastid data matrices were subjected to Maximum Parsimony analyses. Results and Conclusions: Molecular data that were obtained in this study in...

The antioxidant capacity tests were designed to evaluate the antioxidant activities of methanol extracts. Total phenolic and flavonoid concentrations of each extract were also determined by using both Folin-Ciocalteu reagent and aluminum chloride. The aerial part was found to possess the highest total phenolic content (146.30 ± 4.58 mg GAE/g) and total antioxidant capacity (175.33 ± 3.98 mg AE/g). The essential oil from root and aerial parts was analyzed by gas chromatography mass spectroscopy (GC-MS) systems. The major components identified were n-hexadecanoic acid, hexahydro farnesyl acetone, α-caryophyllen, hexanal and phytol. In fatty acid profiles of plant, palmitic, stearic, oleic and linoleic acid were detected as the main components. The results of this study have shown that the ext...
