  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.

  Antioxidant Activities of Different Peanut (Arachis hypogaea L.) Market Types by Spectrophotometric Techniques Combined with Chemometrics

  Gıdık, Betül; Can, Zehra; Önemli, Fadul

  Peanut is rich in oil and protein and has a large content of bioactive constituents consisting of tocopherols, phytosterols, and so on. Generally, Virginia, Spanish, Valencia and Runner market types are grown of peanut. In this study, it is aimed to determine the antioxidant activity, total phenolic content and total flavonoid content of peanuts from four different market types, for the first time, and group them with principal component analysis (PCA) and hierarchical cluster analysis (HCA). For PCA, PC1 and PC2 explained 87.655 % of the total variation and, according to the HCA of peanut samples, two main groups were determined. The total phenolic content changed 1.556 to 2.899 mg GAE/g. The lowest value have seen at Spanish merket type to determine the antioxidant activities of peanut samples were maked FRAP and DPPH assay, the lowest FRAP value (8.136 μmol FeSO47H2O/g sample) was seen at Valencia market type, the highest (14.004 μmol FeSO47H2O/g sample) was seen at Virginia market type. It was determined that the total flavonoid, total phenolic content, and antioxidant activities of the Virginia, Valencia, Spanish, and Runner market types included in the study were different from each other, and the Virginia market type showed superior characteristics compared to the others. The results obtained suggest that Virginia market type may be preferred more especially in peanut cultivation for food uses. It is thought that this study can be a source for future studies by eliminating a deficiency in the literature.

  Antioxidant, antimicrobial activities and fatty acid compositions of wild berberis spp. by different techniques combined with chemometrics (PCA and HCA)

  Gıdık, Betül

  Interest in medicinal plants and fruits has increased in recent years due to people beginning to consume natural foods. This study aims to investigate the total phenolic flavonoid content, antiox-idant activity, condensed tannin content, oil content, and fatty acid compositions of five local breeds of Berberis spp. from Bayburt, Turkey, and their antioxidant and antimicrobial activities. The fatty acid composition of samples was performed with gas chromatography-mass spectrometry (GC-MS), and the total fatty acid content of samples was between 6.12% and 8.60%. The main fatty acids in Berberis spp. samples were α-linolenic acid (32.85–37.88%) and linoleic acid (30.98–34.28%) followed by oleic acid (12.85–19.56%). Two antioxidant assays produced similar results, demonstrating that extracts of wild B. vulgaris L. had the highest ferric reducing antioxidant power (FRAP) (621.02 µmol FeSO4.7H2O/g) and 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) (0.10 SC50 mg/mL) values. According to principal component analysis (PCA), four components were determined. In addition, two main groups were determined according to hierarchical cluster analysis (HCA), and wild and culture of B. vulgaris L. were in different subgroups. This is the first original report about the fatty acid composition and oil content of Berberis spp. grown in Bayburt, Turkey. The obtained results indicate that B. integerrima Bunge and B. vulgaris, which have especially remarkable fatty acid content, antioxidant, and antimicrobial activity, could be potential sources for these properties in different areas of use.
