“…Chromosome number data are powerful source along taxonomy, pollen morphology and molecular studies to establish natural groups in complex taxa (Soltis 2014). Regarding the complexity within the Arctium-Cousinia group, karyology has provided useful information to understand the karyological evolution and natural classification of this group (Susanna et al 2003a). Considering the literature (Djavadi 2007, 2012, Djavadi and Attar 2010, Sheidai et al 2012, Parishani et al 2014, up to now chromosome number reports are existed for about 120 species of Cousinia belonging to flora of Iran.…”

New Chromosome Counts in <i>Cousinia</i> (Asteraceae) from Flora of Iran

2017

In this study, we report the chromosome number on the eight Cousinia species belonging to six sections distributed in south east and north east parts of Iran. Seven of the counts are new to science and one provides confirmation of the previous report. The results of this study are the first reports of the basic chromosome number within sect. Spinuliferae and sect. haussknechtianae. The present study reports x=12 for C. lasiolepis from sect. Alpinae which is new for the material originated from flora of Iran. The result of this study also confirmed the previously reported basic chromosome number of x=13 which had been supposed to be erroneous for sect. Leiocaules.

A comprehensive phytochemical investigation of aerial parts obtained from Centaurea sicula L. led to the isolation of 14 terpenoids (1−14) and nine polyphenols (15−23). The sesquiterpenoid group (1−11) included three structural families, namely, elemanolides (1−6), eudesmanolides (7 and 8), and germacranolides (9−11) with four unreported secondary metabolites (5−8), whose structure has been determined by extensive spectroscopic analysis, including 1D/2D NMR, HR-MS, and chemical conversion. Moreover, an unprecedented alkaloid, named siculamide (24), was structurally characterized, and a possible biogenetic origin was postulated. Inspired by the traditional use of the plant and in the frame of ongoing research on compounds with potential activity on metabolic syndrome, all the isolated compounds were evaluated for their stimulation of glucose uptake, disclosing remarkable activity for dihydrocnicin (10) and the lignan salicifoliol (15).Centaurea is one of the most emblematic plant genera of the Mediterranean area, and with its hundreds of species (between 500 and 700, depending on the classification used), it is among the most numerous and taxonomically complex in the Cardueae tribe of the Asteraceae family. Centaurea plants can be annual, biennial, or perennial, rarely dwarf shrubs, with usually unarmed leaves. Along with the Iranian region, the Mediterranean area is one of the hotspots of distribution of the genus. 1−5 Considering this botanical richness, it is not surprising that several Centaurea species have long been used in folk medicine for a variety of ailments, such as treatment of diabetes, diarrhea, hypertension, headache, muscle pains, microbial infections, rheumatism, and malaria. 6 Compounds virtually belonging to dozens of classes of secondary metabolites have been characterized in Centaurea species, but, undoubtedly, sesquiterpene lactones, 7,8 flavonoids, 9 and alkaloids 10 are the hallmark of this genus.Centaurea sicula L. is a Mediterranean species distributed in Spain, Southern Italy, Malta, Tunisia, and other countries of Northwestern Africa. 11 In Sicily, the Italian region that gives the name to the species, it is widespread in the uncultivated lands. 12 Previous phytochemical investigations on this plant have reported the occurrence of sesquiterpene lactones, 13,14 flavonoids, 15 acetylenes, 16 and its essential oil composition. 17 Recently, the antioxidant properties of the plant extracts of specimens collected in Tunisia have been investigated. 18 In the frame of our research project aimed at the phytochemical profiling of species of the genus Centaur-
