    Determination of fingerprints contents of different extracts and parts of six endemic Salvia taxa by GC-MS: Source species for valuable compounds with drug or drug potential
    (Wiley, 2022) Akdeniz, Mehmet; Yener, İsmail; Dinçel, Demet; Fırat, Mehmet; Değirmenci, Dilek Karataş; Ertaş, Abdulselam
    Public use of Salvia species and their importance in the scientific world is continually increasing. It is known that this use and the importance of Salvia species are mostly due to the terpenoid compounds that they contain. In this context, the terpenoid-steroid-flavonoid contents of extracts of six endemic Salvia (S. kurdica, S. pseudeuphratica, S. rosifolia, S. siirtica, S. cerino-pruinosa var. cerino-pruinosa and S. cerino-pruinosa var. elazigensis) species prepared with different solvents were determined by gas chromatography-mass spectrometry. Within the framework of the ingredient analysis, content analysis of the ethanol extracts of the root, branch, leaf and flower parts of the species collected in the same period between 2015 and 2017 years was performed. In general, extracts prepared with chloroform and ethanol were found to contain a wide variety of compounds while petroleum ether extracts were found to contain much less varied compounds. In addition, in general, root extracts are richer in terpenoid compounds than aerial part extracts. Some species can be used as source species in terms of ferruginol, cryptanol, 6,7-dehydroroyleanone, lup-(20)29-ene-2 alpha-hydroxy-3 beta-acetate, salvigenin and beta-sitosterol contents (52,114.28, 75,979.08, 101,247.41, 40,071.29, 33,952.13 and 34,010.90 mu g analyte/g extract, respectively).

    Molecular analysis of grapevine germplasm by SSR (Simple Sequence Repeats) in Diyarbakir province, Turkey
    (Corvinus University of Budapest, 2019) Karataş, Hüseyin; Karaaǧaç, Eda; Değirmenci, Dilek Karataş; Ağaoğlu, Sabit
    This study was aimed to identify the grape cultivars growing in Diyarbakir. A total of 45 genotypes were analyzed using 7 microsatellite loci. The numbers of alleles per locus ranged between 7 and 10, whereby VVS2 and VrZAG47 had the highest and VVMD7, VrZAG62, and VrZAG79 had the lowest number of alleles. The expected and observed heterozygosity were 0.77 and 0.73, respectively. Clustering analysis was performed using the UPGMA method (Unweighted Pair-Group Method using Arithmetic means). A dendrogram was constructed based on the genetic similarity among the genotypes, which indicated 5 distinct groups, with each group involving numerous subgroups. Two additional genotypes that are used as reference genotypes around the world, Cabernet Sauvignon and Merlot, were also analyzed and were classified into a separate subgroup and differentiated from the other 43 genotypes. In conclusion, synonyms and homonyms were detected among some of the genotypes analyzed in the study.
