Background: Many species of the genus Centaurea have been reported to be used in Anatolian folk medicine. In present study, methanolic and aqueous extracts three L. (C. calcitrapa subsp. calcitrapa, C. ptosimopappa spicata) assessed for antioxidant cytotoxic activities. Materials Methods: Antioxidant activity was investigated by DPPH superoxide anion scavenging anti-lipid peroxidation assays. Cytotoxic effect on HeLa Vero cells were MTT assay. Results: Superoxide activities higher than those...
Boraginaceae plants, including four endemic species from Türkiye, were analyzed for organic and inorganic compositions using inductively coupled plasma mass spectrometry (ICP-MS) liquid chromatography-mass spectrometry/mass (LC-MS/MS) to explore their nutritional, medicinal, ecological significance. This study examined 18 species, identifying key elements, such as sodium (87 600.359-118 049.272 g/kg), potassium (98 876.885-145 587.899 iron (70 396.436-116 416.076 which showed significant...

Quantitative determination secondary metabolites most effective samples plant...
This article investigates the seed exomorphic characteristics of 14 taxa Lepidium L. in Brassicaceae by light microscope and scanning electron (SEM). The are size, shape, colour, wings, surface pattern. All seeds described, illustrated, compared this article. results SEM at higher magnification showed 6 types patterns: tuberculate, reticulate, ruminate, reticulate-tuberculate, reticulate-areolate, reticulate-fovate. In these patterns, there were diagnostic differences specific level for Lepidium.
We investigated the chromosome number and morphology of five Centaurea species belonging to different sections. All material analyzed was diploid with 2n = 18 or 20. Chromosome found for two populations (specimen a specimen b) cassia Boiss., rare from Sect. Jacea (Mill.) DC., C. ptosimopappa Hayeka, local endemic Ptosimopappus O. Hoffm. A 20, however, observed other three species: arifolia Cynaroides Boiss. ex Walp., antochia var. antochia, an variety Acrocentron (Cass.) hyalolepis...
This article investigates the exomorphic characteristics of achenes which are achene size, color, and surface pattern, pappus length, colour. All these in seven taxa Asteraceae namely, C. aggregata Fisch. & C.A. Mey. ex DC. subsp. aggregata, sivasica Wagenitz, polypodiifolia Boiss. var. polypodiifolia, szowitziana (Boiss.) iberica Trev. Spreng, urvillei stepposa carduiformis described, illustrated compared. The results SEM at higher magnification showed three types patterns:...
Centaurea malatyensis Ş. Kültür & M. Bona sp. nova (Asteraceae) is described as new to science from East Anatolia (B6: Malatya: Turkey). It morphologically similar C. leptophylla but differs mainly in its stem, basal and cauline leaf shape size, achene, pappus phyllary appendages. The geographical distribution of the species relatives mapped. ecology conservation status also presented. Micromorphological structures achenes are examined by SEM.
In this study, the cypsela micro-macromorphological characteristics of 15 Centaurea L. taxa, from seven sections Turkey were investigated using Light Microscopy and Scanning Electron techniques. The studied taxa are C. goksivriensis M. Bona, calcitrapa subsp. L., cilicica (Boiss. & Bal.) Wagenitz, glastifolia amanicola Hub.-Mor., cataonica Boiss. Hausskn. in Boiss., haradjianii haussknechtii regia var. regia, sclerolepis spicata solstitialis behen rigida Banks Sol., antitauri Hayek. They...

It morphologically similar to C. cheirolopha (Fenzl) Wagenitz, lycopifolia Boiss. & Kotschy ex Kotschy, stevenii Bieb. (Section Pseudoseridia), but it differs mainly in life form, general habit, leaves achene characters. The IUCN conservation status Critically Endangered (CR) should be applied amanosensis.
Centaurea goksivriensis M. Bona, a new species of C. sect. Acrocentron from Hatay Province Turkey, is described and illustrated. It morphologically similar to antiochia var. antiochia, carduiformis, urvillei subsp. armata but differs mainly in its flower colour, indumentum pappus. The IUCN conservation status Critically Endangered (CR) should be applied goksivriensis.
Centaureaziganensis Yüzb., M. Bona & İ. Genç, a new species is described and illustrated from Gümüşhane province, NE Turkey.
