Publication Open Access Investigation of Bioactive Components, Antioxidant and Antimicrobial Activities of Traditional Turkish Beverage Hardaliye(2022-01-01T00:00:00Z) POLAT SARI, SİLVA; DİNÇ, HARİKA ÖYKÜ; BÜYÜKKILIÇ ALTINBAŞAK, BETÜL; YÜKSEL MAYDA, PELİN; AKGÜL, ÖZER; SAPMAZ, BURCU; ÖNER, YAŞAR ALİ; ÇALIŞKAN, REYHAN; DİNÇ, HARİKA ÖYKÜ; BÜYÜKKILIÇ ALTINBAŞAK, BETÜLObjective: In our study, it was aimed to make the chemical analysis of hardaliye products (H1 and H2), which are commercially available by different manufacturers, and to examine their antioxidant and antimicrobial activities. Methods: Antioxidant activity, organic acid and phenolic compounds, and antimicrobial activity in Hardaliye products (H1 and H2) were determined by using 1.1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity, [liquid chromatographyhigh resolution mass spectrometry (LC-HR/MS)] and liquid microdilution methods, respectively. Results: Ascorbic acid and fumaric acid from organic acids were determined by chemical analysis of hardaliye samples by LC-HR/ MS method. While ascorbic acid concentrations were 21.295 mg/L and 26.84 mg/L in H1 and H2, respectively, fumaric acid concentrations were 59.55 mg/L in H1, and 224.562 mg/L in H2. While the phenolic component with the highest concentration in H1 was resveratrol (44.57 mg/L), it was observed that the phenolic component with the highest concentration in H2 was p-coumaric acid (31.87 mg/L). In terms of antioxidant activity, diphenyl-2- picrylhydrazylfree radical scavenging activity of hardaliye samples was determined as 2.07±0.004% and 2.49±0.004% in H1 and H2, respectively. It was determined that hardaliye samples showed inhibitory effect [H1 minimum inhibitor concentration (MIC): 15.625 µg/mL, H2 MIC: <3.9 µg/mL] against only S. Epidermidis ATCC 49461 strains among the tested microorganisms. Conclusion: In our study, it was determined that two different commercial Hardaliye products contained very low concentrations of phenolic compounds compared to the data in the literature, and therefore it was thought that tested Hardaliye products did not show antioxidant activity.Publication Metadata only Fruit Anatomical and Morphological Characteristics of Endemic Daucus conchitae W.

Methods: The essential oil obtained by the hydrodistillation method was analyzed by gas chromatography-mass spectrometry systems. The antimicrobial activities of the essential oil were evaluated by disc diffusion and resazurin microplate methods, the anticholinesterase effect was determined by using in vitro AChE and BChE enzymes inhibition assays, and the antioxidant effect was evaluated by ABTS and CUPRAC methods. Results: The main components of the essential oil were determined as styrene (92.6%) and α-pinene (2.2%). The essential oil showed weak antimicrobial activity against K. pneumoniae, S. epidermidis but strong antimicrobial activity against A. baumannii, C. glabrata. It showed moderate inhibitory activity to AChE and BChE enzymes, and IC50 values were calculated as 36.5 μg/mL and 69.5 μg/mL, respectively. It also showed low inhibition of α-glucosidase (IC50 value was 637.2 μg/mL) and a similar antioxidant effect in the CUPRAC and ABTS method (A0.5 value was 637.2 μg/mL and IC50 value was 632.2 μg/mL, respectively). Conclusion: Styrax Liquidus essential oil can be considered a natural antimicrobial agent due to its strong antimicrobial activity capacity against A. baumannii and C. glabrata strainsPublication Metadata only Composition and Biological Activities of Pimpinella anisetum Boiss.
