Chemical characterization and biological activities of the genus Tanacetum (Compositae)
Bioactive Natural Products (Part H), 2002Co-Authors: Nezhun Goren, Nazlı Arda, Zerrin CaliskanAbstract:The genus Tanacetum has been used as medicinal plants for over 2000 years. Interest in the genus has been stimulated by its biological activities, particularly as insect antifeedants, antitumor and antimicrobial activities due to its sesquiterpenoid constituents. The genus Tanacetum is represented by c.a.70 species in the worldand by 44 in Turkey. It is an Asia centered genus whichis widespread in the Northern Hemisphere and temperate regions. Tanacetum species contain mainly sesquiterpenoids and flavonoids, whereas the other terpenoids and phenolic compounds are rarely found. Sesquiterpenoids which are the main constituents of the genus, supposed to be bioactive principles of the plants. Flavonoids and essential oils are also pointed out as active substances in some species. On the other hand,there is a confusion on the systematic position and classification of several species of Asteraceae, therefore chemotaxonomy of the species will help the systematic studies. Since the importance of sesquiterpenes, sesquiterpene lactones and flavonoids from the chemosystematic and the biological point of views, especially the chemistry and the biological activities of these compounds will be reviewed in this chapter, whilethe essential oils and the acetylenic compounds will not be mentioned.

Achene micromorphology in Tanacetum (Asteraceae-Anthemideae) and its taxonomic and phylogenetic implications
Flora - Morphology Distribution Functional Ecology of Plants, 2016Co-Authors: Ali Moradi Behjou, Ali Sonboli, Hossein Riahi, Shahrokh Kazempour OsalooAbstract:Achene morphology of 37 taxa of Tanacetum, Ajania semnanensis, and Artemisia paradoxa were investigated using light- and scanning electron microscopy to evaluate the diagnostic value of such characters in infrageneric classification and to provide additional evidence on the delimitation of taxa. In this study, 26 quantitative and qualitative characteristics were examined using multivariate analysis. Cluster analysis and principal component analysis of the data showed that achene characters have significant value for separation of species from one another and support delimitation at the sectional level. The results revealed that the genus Tanacetum is separated into two main groups having either a coroniform or unilateral pappus. The congruency of micromorphological and molecular studies is discussed and evolutionary trends of some micromorphological traits are evaluated.

the striking and unexpected cytogenetic diversity of genus Tanacetum l asteraceae a cytometric and fluorescent in situ hybridisation study of iranian taxa
BMC Plant Biology, 2015Co-Authors: Nayyereh Olanj, Ali Sonboli, Teresa Garnatje, Joan Valles, Sonia GarciaAbstract:Although karyologically well studied, the genus Tanacetum (Asteraceae) is poorly known from the perspective of molecular cytogenetics. The prevalence of polyploidy, including odd ploidy warranted an extensive cytogenetic study. We studied several species native to Iran, one of the most important centres of diversity of the genus. We aimed to characterise Tanacetum genomes through fluorochrome banding, fluorescent in situ hybridisation (FISH) of rRNA genes and the assessment of genome size by flow cytometry. We appraise the effect of polyploidy and evaluate the existence of intraspecific variation based on the number and distribution of GC-rich bands and rDNA loci. Finally, we infer ancestral genome size and other cytogenetic traits considering phylogenetic relationships within the genus. We report first genome size (2C) estimates ranging from 3.84 to 24.87 pg representing about 11 % of those recognised for the genus. We found striking cytogenetic diversity both in the number of GC-rich bands and rDNA loci. There is variation even at the population level and some species have undergone massive heterochromatic or rDNA amplification. Certain morphometric data, such as pollen size or inflorescence architecture, bear some relationship with genome size. Reconstruction of ancestral genome size, number of CMA+ bands and number of rDNA loci show that ups and downs have occurred during the evolution of these traits, although genome size has mostly increased and the number of CMA+ bands and rDNA loci have decreased in present-day taxa compared with ancestral values. Tanacetum genomes are highly unstable in the number of GC-rich bands and rDNA loci, although some patterns can be established at the diploid and tetraploid levels. In particular, aneuploid taxa and some odd ploidy species show greater cytogenetic instability than the rest of the genus. We have also confirmed a linked rDNA arrangement for all the studied Tanacetum species. The labile scenario found in Tanacetum proves that some cytogenetic features previously regarded as relatively constant, or even diagnostic, can display high variability, which is better interpreted within a phylogenetic context.

Effects of Hydroalcoholic Extract of Tanacetum Sonbolii (Asteraceae) on Pain-related Behaviors during Formalin Test in Mice
Basic and clinical neuroscience, 2014Co-Authors: Mohammad Sofiabadi, Ali Sonboli, Hassan Azhdari-zarmehri, Firouzeh Naderi, Mohadeseh Ghalandari-shamami, Abbas HaghparastAbstract:INTRODUCTION Tanacetum sonbolii (Asteraceae) is an endemic species in Iran. In the present study, we examined the effects of Tanacetum sonbolii hydroalcoholic extract on the formalin test in mice. METHODS 126 Swiss albino mice weighing 230-280g were used as subjects. The formalin test was performed on two control groups (marked as intact and saline groups; n = 6 in each group) and an experimental group. In all groups, the formalin test was recorded for 60 min after administration of extract and drugs in mice. RESULTS The results showed that Tanacetum sonbolii (150 and 300 mg/kg) produced significant antinociception in phase 2. In addition, different doses of Tanacetum sonbolii extract (600, 900 and 1200 mg/kg) also induced antinociceptive effects in phase1 and phase 2. On the other hand, morphine could induce antinociception in a dose-dependent manner. Diclofenac (10 mg/kg) failed to affect the pain scores compared to Tanacetum sonbolii (300 mg/kg) group. DISCUSSION It seems that administration of hydroalcoholic extract of Tanacetum sonbolii has the potential to relieve pain through both central and peripheral mechanisms in persistent inflammatory nociception.

Karyomorphological study of nine Tanacetum taxa (Asteraceae, Anthemideae) from Iran
Caryologia, 2013Co-Authors: Nayyereh Olanj, Ali Sonboli, Hossein Riahi, Shahrokh Kazempour OsalooAbstract:Chromosome number and morphology in nine taxa belonging to 10 populations of Tanacetum L. (Asteraceae) were investigated using karyological techniques. The chromosome number found in eight species was 2n = 18 (T. balsamita, T. budjnurdense, T. sonbolii, T. archibaldii, T. persicum, T. parthenium and T. canescens) while T. polycephalum subsp. duderanum and T. polycephalum subsp. azerbaidjanicum had 2n = 36. Six records are new while four records confirmed the previous data. At mitotic metaphase, all chromosomes had median point (M), median region (m), submedian (sm) or subterminal (st) centromeres. The karyotypes are classified in types 2A or 2B, showing the presence of a primitive symmetrical karyotype in the genus Tanacetum. An updated checklist of karyological data of the genus is also presented.

molecular phylogeny and taxonomy of Tanacetum l compositae anthemideae inferred from nrdna its and cpdna trnh psba sequence variation
Plant Systematics and Evolution, 2012Co-Authors: Ali Sonboli, Kathrin Stroka, Shahrokh Kazempour Osaloo, Christoph OberprielerAbstract:The genus Tanacetum L. consists of around 160 species of the Compositae-Anthemideae. It holds a crucial position for understanding the phylogeny of the tribe and its subtribal and generic classification. The present study focuses on the phylogenetic relationships of the species and aims at a discussion of the infrageneric classification and boundaries of the genus. Sequence information from a nuclear [nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS)] and a chloroplast marker [chloroplast DNA (cpDNA) trnH–psbA] was used to infer the phylogeny of Tanacetum and many representatives of closely related genera. Bayesian inference methods were used for the phylogenetic reconstructions based on a combined dataset including both sequence and indel information. Contrasting the high morphological diversity in the genus, sequence divergence among Tanacetum representatives included was found to be very low, leading to unresolved phylogenetic relationships within the genus. Nevertheless, the generic separation of Tanacetum from other members of subtribe Anthemidinae (i.e., Anthemis, Archanthemis, Cota, Nananthea, and Tripleurospermum) emerges, while other, presently accepted genera are found nested in Tanacetum (i.e., Gonospermum, Lugoa, and Xylanthemum). Finally, the phylogenetic independence of the SW European T. microphyllum from the rest of Tanacetum and the other genera of Anthemidinae is found to receive strong support and is also backed by its morphological uniqueness. The new genus Vogtia Oberpr. et Sonboli is described to accommodate Tanacetum microphyllum and the closely related species T. annuum. The sinking of Gonospermum, Lugoa, and Xylanthemum into a broadly circumscribed genus Tanacetum is proposed until more stable phylogenetic reconstructions based on more and more variable molecular markers are possible. Concerning the infrageneric classification of Tanacetum, the phylogeny does not support the separation of the white- and red-rayed species (the former genus Pyrethrum) from the discoid, disciform, or yellow-rayed ones (i.e., Tanacetum in the strict sense) at any infrageneric rank. The hypothesis by Tzvelev (1961) that the yellow-rayed representatives may have evolved from disciform ancestors receives little support.
