    Yagi, Sakina; Zengin, Gokhan; Ibrahime Sinan, Kouadio; Yavuz Paksoy, Mehmet; Cziáky, Zoltán; Jekő, József; Dall'Acqua, Stefano

    The present study aimed to investigate the chemical constituents of different extracts from aerial parts of A. absinthium and to evaluate their antioxidant and enzyme inhibition activity. Extracts were prepared by maceration, infusion or Soxhlet techniques. Results showed that the highest total phenolic and flavonoids contents was recorded respectively from the hexane extract prepared by maceration and ethyl acetate extract obtained by Soxhlet method. The characteristic compounds of Artemisia species artemetin, casticin, sesartemin and yangambin in addition to coumarins were identified in all extracts. Aqueous extract obtained by infusion exerted the highest radical scavenging and ions reducing properties while that prepared by maceration displayed the highest chelating power. Methanol extracts obtained by the two methods of extraction exerted the highest anti-Tyr activity while that obtained by maceration showed the best α-glucosidase inhibition activity. These findings indicated that A. absinthium is a rich source of bioactive molecules with possible therapeutic applications.

    Investigation of Antimicrobial, Anti-Quorum Sensing, and Cytotoxic Activities of Flavonoids Isolated from Pulicaria armena Boiss. & Kotschy ex Boiss. (Asteraceae)

    Başpınar, Yasemin; Gürbüz, Perihan; Dilem Doğan, Şengül; Gözde Gündüz, Miyase; Aleksic, Ivana; Vojnovic, Sandra; Nikodinovic-Runic, Jasmina; Yavuz Paksoy, Mehmet

    This is the first report on the separation and biological assessment of all metabolites derived from Pulicaria armena (Asteraceae) which is an endemic species narrowly distributed in the eastern part of Turkey. The phytochemical analysis of P. armena resulted in the identification of one simple phenolic glucoside together with eight flavon and flavonol derivatives whose chemical structures were elucidated by NMR experiments and by the comparison of the spectral data with the relevant literature. The screening of all molecules for their antimicrobial, anti-quorum sensing, and cytotoxic activities revealed the biological potential of some of the isolated compounds. Additionally, quorum sensing inhibitory activity of quercetagetin 5,7,3’ trimethyl ether was supported by molecular docking studies in the active site of LasR which is the primary regulator of this cell-to-cell communication system in bacteria. Lastly, the critical molecular properties indicating drug-likeness of the compounds isolated from P. armena were predicted. As microbial infections can be a serious problem for cancer patients with compromised immune systems, this comprehensive phytochemical research on P. armena with its anti-quorum sensing and cytotoxic compounds can provide a new approach to the treatment.

    Genetic Relationship of Seven Endemic Inula L. (Asteraceae) Species Grown in\rTurkey

    Paksoy, Mehmet Yavuz; Sevindik, Mustafa; Sevindik, Emre

    In this study, genetic relationship of ISSR markers of seven endemic Inula species distributed in\rTurkey was carried out. Plant samples were collected from different regions of Turkey in 2013 and\rgDNA was obtained by DNA isolation from green leaves. Genetic relationship between species was\rdetermined using 12 ISSR primers. PCR products were run on agarose gel electrophoresis and\rvisualized under UV light. All gel images were examined and the presence and absence of\rpolymorphic bands were scored as 0 and 1. A total of 85 bands were obtained from the primers. Of\rthese, 74 polymorphic and 11 monomorphic bands were obtained. The total polymorphism rate was\rfound to be approximately 87.05%. The phylogenetic tree and genetic distances between species\rwere calculated using the PAUP 0 4.0b10 analysis program. According to the distance matrix, the\rgenetic distance was found between the closest Inula helenium subsp. orgyalis and Inula helenium\rsubsp. vanensis (0.29851), while the farthest between Inula sarana and Inula macrocephala\r(0.56000) species. The phylogenetic tree was obtained using the UPGMA algorithm, and the tree\rconsisted of two groups. The results were compared with the morphological, palynological nrDNA\rand cpDNA results of the past. Our findings supported previous studies

    MICROMORPHOLOGICAL AND ANATOMICAL INVESTIGATIONS ON CONRINGIA HEIST. EX FABR.

    Selvi, Selami; Aladi, Hatice Inci; Paksoy, Mehmet Yavuz

    The micromorphological and anatomical investigations on 6 taxa of Conringia Heist. ex Fabr. growing in Turkey were carried out. The anatomy of root, stem and leaves was examined in detail. In micromorphological studies stem and leaf surface of species was examined. Mesophyll type of lamina is dorsiventral (Conringia planisiliqua, C. persica, C. austriaca) and equifacial (C. clavata, C.grandiflora, C. orientalis). Stomata situated on both surfaces, are anisocytic and rarely anomocytic types. Crystals of calcium oxalate observed in only one species (C. grandiflora) was found to have cubic type parenchyma cells of the stem and leaf In micromorphological studies the surface of the stem and leaves were found to be glabrous. Epidermal surface of leaves was observed to be covered with waxy cuticular particles. Anticlinal walls of the adaxial cells are undulate and rarely straight and anticlinal walls of abaxial epidermis are undulate and rarely sinuate. Periclinal walls were found to be covered with upper waxy layer which was flat. A diagnostic key based on combined stem, leaf and leaf epidermal characteristics are presented. The leaf mesophyll structures, stem vascular bundles number, lignified or unlignified of sclerenchyma, epidermal surface and absence or presence of crystals were found to be important characters for the identification of Conringia species.

    Paksoy, Mehmet Yavuz; Sevindik, Emre; Uzun, Sefa

    In this study, we performed a genetic diversity using RAPD markers for some Dittrichia viscosa populations grown in the Aydın region of Turkey. Total genomic DNA isolation from the leaves of Dittrichia viscosa was performed using commercial kit. eight RAPD primers were used to determine genetic diversity among populations. Polymerase Chain Reaction (PCR) was performed with all DNA samples and primers with ability of scoreing band. PCR products were run in agarose gel and visualized under UV light. They scored as there were bands (1) and no bands (0) at all gel images and their files were created. A total of 50 characters were obtained from the primers. Phylogenetic relationships and genetic distances between the cultivars were calculated by using the PAUP* 4.0b10 analysis program. According to the PAUP data, the closest genetic distance was determined 0.20000 and between Central and İncirliova populations, the most distant genetic distance were determined 0.36842 between İncirliova and Koçarlı populations. In the phylogenetic analysis has been obtained using UPGMA algorithms and phylogenetic tree consist of two clades. The results also propose that RAPD markers are useful tools for indicating genetic relationships among Dittrichia viscosa populations.

    Paksoy, Mehmet Yavuz; Sevindik, Emre; Topseçer, Feyzanur; Aydoğan, Melike

    In this study, we performed a genetic diversity analysis using RAPD (Random AmplifiedPolymorphic DNA) and ISSR (Inter simple sequence repeat) markers for some Chrysochamelaspecies growing in Turkey. PCR was performed using RAPD and ISSR primers and genomic DNAsamples from each specimen, and the resulting bands were scored. Phylogenetic relationships andgenetic distances between the studied taxa were calculated using the PAUP analysis program.According to the RAPD analysis, the closest genetic distance was found to be 0.20000 between C.noeana populations, while the most distant values were found as 0.60000 between C. noeana and C.elliptica. The ISSR analysis also revealed the closest genetic distance as 0.34043 between C. noeanapopulations, while the most distant values were found to be 0.55319 between C. noeana and C.elliptica. UPGMA (unweighted pair group method with arithmetic mean) dendrogram generated forboth RAPD and ISSR analyses consisted of two groups. As a result, it was found that RAPD datawere more appropriate for comparison with the previous anatomical and morphological data of the studied taxa.
