    Background and aim: In this study, it was aimed to examine the relationship between COVID-19 phobia and adherence to the MD in university students. Materials and Methods: This research in cross-sectional design was conducted with 351 students studying at Alanya Alaaddin Keykubat University located in the Mediterrenan region of Türkiye between September 2021 - December 2021. The data was collected using Personal Information Form, Mediterranean Diet Adherence Scale (MEDAS) and COVID-19 Phobia Scale. Results: The study included a total of 351 students 254 females (72.4%) and 97 males (27.6%) with a mean age of 20.4 ± 2.1 years. When the relationship between the MEDAS score and various variables was examined, no significant relationship was found between gender, smoking, BMI and meal skipping (p>0.05), while the MEDAS score of those with high income status was found to be significantly higher than those with low income status (p<0.05). There was a strong negative correlation between the MEDAS score and COVID-19 Fobia Scale and its subgrups. It was observed that as the COVID-19 Fobia Scale scores increase, the MEDAS scores decrease (p < 0.05). Conclusion: Especially during the pandemic period, both the awareness level of the society on healthy nutrition should be increased and its implementation as a lifestyle should be supported. This situation can reduce the fear and phobia in the society. © Mattioli 1885.

    Phenolic compounds, essential oil composition, and antioxidant activity of Angelica purpurascens (Ave-Lall.) Gill
    (2021) Türkuçar, Semra Alkan; Karaçelik, Ayça Aktaş; Karaköse, Mustafa
    In this study, methanol extracts (MEs) and essential oil (EO) of Angelica purpurascens (Ave-Lall.) Gill obtained from different parts (root, stem, leaf, and seed) were evaluated in terms of antioxidant activity, total phenolics, compositions of phenolic compound, and essential oil with the methods of 2,2-azino-bis(3ethylbenzo-thiazoline-6-sulfonic acid (ARTS center dot(+)), 2,2-diphenyl-1-picrylhydrazil (DPPH center dot) radical scavenging activities, and ferric reducing/antioxidant power (FRAP), the Folin-Ciocalteu, liquid chromatography tandem mass spectrometry (LC-MS/MS), and gas chromatography-mass spectrometry (GC-MS), respectively. The root extract of A. purpurascens exhibited the highest ABTS center dot(+), DPPH center dot, and FRAP activities (IC50: 0.05 +/- 0.0001 mg/mL, IC50: 0.06 +/- 0.002 mg/mL, 821.04 15.96 mu M TEAC (Trolox equivalent antioxidant capacity), respectively). Moreover, EO of A. purpurascens root displayed DPPI scavenging activity (IC50: 2.95 +/- 0.084 mg/mL). The root extract had the highest total phenolic content (438.75 +/- 16.39 GAE (gallic acid equivalent), mu g/mL)). Twenty compounds were identified by LC-MS/MS. The most abundant phenolics were ferulic acid (244.39 +/- 15.64 mu g/g extract), benzoic acid (138.18 +/- 8.84 mu g/g extract), oleuropein (78.04 +/- 4.99 mu g/g extract), and rutin (31.21 +/- 2.00 mu g/g extract) in seed, stem, root, and leaf extracts, respectively. According to the GC-MS analysis, the major components were determined as alpha-bisabolol (22.93%), cubebol (14.39%), alpha-pinene (11.63%), and alpha-limonene (9.41%) among 29 compounds. Consequently, the MEs and EO of A. purpurascens can be used as a natural antioxidant source.
