This study provides a comprehensive phytochemical, elemental, and spectroscopic characterization of 26 species belonging to the Asteraceae family, several of which are endemic to T & uuml;rkiye and traditionally used in folk medicine. Qualitative screening revealed the widespread presence of flavonoids, saponins, tannins, and carbohydrates, while alkaloids and anthracene heterosides were entirely absent in all taxa. Among the species analyzed, Cichorium intybus, Cyanus depressus, Achillea arabica, and Cirsium davisianum exhibited the richest phytochemical diversity, suggesting strong biological potential. Quantitative evaluation showed that Klasea serratuloides possessed the highest total phenolic content (99.49 mu g GAE/mg extract), followed by Artemisia scoparia and Inula sarana, indicating notable antioxidant potential. Elemental analysis by ICP-MS demonstrated significant interspecies variation, with Centaurea armena, Centaurea arvensis, and Cichorium intybus containing elevated levels of essential macro- and trace elements such as K, Mg, Ca, Zn, and Se, whereas Helichrysum plicatum and Scorzonera ulrichii showed high Co and Se contents. Conversely, trace levels of potentially toxic elements (e.g., Al, U) were detected in some taxa, emphasizing the need for careful evaluation of their pharmacological use. FTIR analysis confirmed the presence of functional groups characteristic of phenolics, flavonoids, tannins, coumarins, and cardioactive heterosides, as indicated by distinct O-H (3200-3600 cm-1), C-H (2850-2950 cm-1), and C=O (1700-1650 cm-1) stretching bands. The combined interpretation of phytochemical and FTIR data underscores the chemical diversity and functional group complexity of these plant extracts. Overall, the results highlight the nutritional and pharmacognostic significance of several Asteraceae species, supporting their potential application in antioxidant, nutraceutical, and therapeutic formulations.

Essential oil content of and phenolic compounds flower-fruit, root, and aerial parts of Heracleum pastinacifolium subsp. incanum were analysed by GC/MS and LC/MS methods, respectively. Antidiabetic, anticholinesterase, and antioxidant activities of flower-fruit, root, aerial parts methanol extracts were evaluated. Apiole (35.0%), myristicine (72.2%), and myristicine (15.1%) were found as major compounds of fruit-flower mixture, root, aerial part essential oils, respectively. Hesperidin was found the highest amount in aerial part and flower-fruit extracts with 8904.2621 ng/mL and 11558.3634 ng/mL values, respectively. Fruit-flower extract showed the highest activity against α-glucosidase (24%). Root extract demonstrating the highest activity (18%) against AChE enzyme. Flowers-fruits mixture methanol extract had a higher % inhibition value on ABTS·+ and DPPH•. Flowers-fruits mixture methanol extract was rich in total phenol, total tannin, and protein content. All the extracts were determined as genetoxically safe according to the results of Ames/Salmonella, Escherichia coli WP2 and Allium cepa assays.
