“…The disorder of the substituent at C-5 was treated analogously to the corresponding description given above. The site occupation factor of the 5-methoxy group refined to 0.904 (5). The hydroxy and water H-atoms were placed in the positions indicated by a difference electron density map and their positions were allowed to refine together with individual isotropic displacement parameters, while restraining the OÀ H distances to 0.84(1) Å.…”

“…Previously, 16 native and one cultivated species of Polygala have been recognized for the Turkish flora (Cullen 1965, Peşmen 1980, Davis et al 1988, Eren et al 2008), but most recently two new species have been identified from the eastern part of Turkey (Dönmez et al 2015, Dönmez and Aydın 2018). It is inferred that the nature of Turkey still hosts many undescribed plant taxa, including Polygala .…”

Morphological and molecular data on a new species of Polygala (Polygalaceae) from Turkey

Polygala fadimeana Dönmez and Çeçen is here described as a new species from the inner part of the Taurus mountain range in Turkey based on morphological data and its phylogenetic position is discussed based on molecular data. This new species is confined to limestone rock walls and is morphologically distinguished from P. kurdica and P. peshmenii by smaller plant size, nearly glabrous leaves, enrolled inner sepals, white colour crest, and other minor diagnostic features. However, a multi‐locus chloroplast phylogeny (trnL‐F and rbcL) including accessions of the new species and related taxa of Turkish Polygala revealed a close relationship to P. pruinosa and P. supina. The taxonomic relationship among the new species and P. kurdica, a poorly known species from Zagros Mountain range, and other closely related species such as P. pruinosa, P. peshmenii and P. supina are discussed. The new species is assessed as critically endangered (CR) based on current knowledge and the distribution of the new species and related taxa is mapped.

“…The genus is represented by 16 native and one cultivated species in Turkey [ 4 , 5 , 6 , 7 ]. Recently, two new species in the subgenus Polygala have been described from the Eastern part of Turkey [ 8 , 9 ]. Among Polygala taxa, P. inexpectata Peşmen & Erik, which is subject to this study, is a narrow endemic species and is known from only the type locality, Ermenek, Turkey.…”

Isolation, Characterization and In Silico Studies of Secondary Metabolites from the Whole Plant of Polygala inexpectata Peşmen & Erik

Polygala species are frequently used worldwide in the treatment of various diseases, such as inflammatory and autoimmune disorders as well as metabolic and neurodegenerative diseases, due to the large number of secondary metabolites they contain. The present study was performed on Polygala inexpectata, which is a narrow endemic species for the flora of Turkey, and resulted in the isolation of nine known compounds, 6,3′-disinapoyl-sucrose (1), 6-O-sinapoyl,3′-O-trimethoxy-cinnamoyl-sucrose (tenuifoliside C) (2), 3′-O-(O-methyl-feruloyl)-sucrose (3), 3′-O-(sinapoyl)-sucrose (4), 3′-O-trimethoxy-cinnamoyl-sucrose (glomeratose) (5), 3′-O-feruloyl-sucrose (sibiricose A5) (6), sinapyl alcohol 4-O-glucoside (syringin or eleutheroside B) (7), liriodendrin (8), and 7,4′-di-O-methylquercetin-3-O-β-rutinoside (ombuin 3-O-rutinoside or ombuoside) (9). The structures of the compounds were determined by the spectroscopic methods including 1D-NMR (1H NMR, 13C NMR, DEPT-135), 2D-NMR (COSY, NOESY, HSQC, HMBC), and HRMS. The isolated compounds were shown in an in silico setting to be accommodated well within the inhibitor-binding pockets of myeloperoxidase and inducible nitric oxide synthase and anchored mainly through hydrogen-bonding interactions and π-effects. It is therefore plausible to suggest that the previously established anti-inflammatory properties of some Polygala-derived phytochemicals may be due, in part, to the modulation of pro-inflammatory enzyme activities.
