Abstract Objectives Saponins are secondary metabolites naturally found in plants with diverse pharmacological properties such as anticancer. This research aimed to explore the anti-cancer of Polygalasaponin XLIV (PS-XLIV) a human colorectal carcinoma cell line derived from Polygala vulgaris roots. Methods HCT166 cells were treated different PS-XLIV concentrations and incubated for 24 48 h. We used immunocytochemistry investigate PS-XLIV’s properties, employing antibodies targeting WNT3A,...
species are frequently used worldwide in the treatment of various diseases, such as inflammatory and autoimmune disorders well metabolic neurodegenerative due to large number secondary metabolites they contain. The present study was performed on
Brassica taxa occur naturally and are also cultivated in Turkey. Due to their economic importance, several cultivars have been extensively certain regions of the country. Alongside extensive cultivation for vegetable production other species genus, juncea has very limited cultivation. Five native known from restricted locations Turkey with only a few collections. Among them, elongata is distributed all over Central Eastern parts country it prefers unfertile soils on hillsides. Highlighting...
The tribe Nigelleae Schröd. (Ranunculaceae) worldwide distribution has been studied taxonomically, based on morphological, palynological and seed morphological characters, as well chromosome counts. Extensive field works have carried out in Turkey, Greece, Iran, Syria, Lebanon, Portugal Northern Cyprus. Moreover, the specimens of major herbaria Ukraine, Russia, Syria Iran Europe examined. This study represents most comprehensive monograph work across its nearly entire distributional range,...

Nine xanthone derivatives (1-9) were isolated from the roots of Polygala azizsancarii, which is a narrow endemic species for flora Türkiye. Based on all evidence, structures 1-9 established as two previously undescribed O-glucosides, 3-O-β-D-glucopyranosyloxy-1,6-dihydroxy-2,5,7-trimethoxyxanthone (1), 3-O-β-D-glucopyranosyloxy-1,6-dihydroxy-2,7-dimethoxyxanthone (2), and seven described xanthones, 1,3,6-trihydroxy-2,5,7-trimethoxyxanthone (3), 1,3,6-trihydroxy-2,7-dimethoxyxanthone (4),...

In this study, capsule and seed features were compared to determine diagnostic traits useful for differentiating taxonomy among 14 Polygala species native Turkey. Capsule morphology of the genus was examined using light scanning electron microscopy. Principal component analysis, ANOVA, Tukey tests used facilitate elucidation relationship between taxa based on quantitative characters. length, wing width, elaiosome shape are taxonomically important morphological species. Moreover, symmetry is...
We examined the seed morphology of Nigella , Garidella and Komaroffia to aid systematics taxonomy. The seeds 21 taxa in 20 species from Mediterranean West Asian countries were studied using both zoom stereo scanning electron microscopy (SEM). Principal coordinate analysis (PCoA) unweighted average linkage (UPGMA) performed assess contribution characters taxonomy tribe. Representative pictures SEM studies measurement are presented. Most showed unique surface sculpturing features, shape, size...
Polygala azizsancarii Dönmez (Polygalaceae) is herein described and illustrated as a new species from Mardin province in SE Turkey. This similar to P. kurdica supina, but it clearly differs by several morphological characters. Diagnostic characters of this are discussed with respect taxonomy illustrations. Conservation status the also assessed according field observations. An updated identification key presented for Turkish genus, which currently includes 18 taxa.
Aubrieta alshehbazii is described as a new species that was collected from rocky steppe of Central Turkey. The sympatric and most similar to A. pinardii, but differs by leaf shape, margin, petiole, indumentum inflorescence. A detailed morphological description, figures comparisons with potentially closely allied are provided herein. assigned CR threat category the IUCN. Beside this, due further studies on type material various taxa, anamasica proposed synonym pinardii
