“…While the antioxidant activity values were lower than those of Karakaya (2023), it was considerably higher than those of other researchers. Antioxidant activity varies depending on genetic structure and environmental factors, cultural practices, harvest time, and stress factors (low and high temperature, drought, diseases, and pests) [8,53,54]. Many of the accessions investigated (particularly S-1 and T-2) were found to possess high antioxidant activity.…”

This study was carried out to determine the fatty acid composition, bioactive compounds, and mineral element content of standard hazelnut cultivars and accessions from the Eastern Black Sea region. A wide variation was determined in terms of the traits examined between hazelnut accessions and cultivars. Most of the accessions investigated had higher values of bioactive compounds, oleic acid, stearic acid, Na, and Ca than the standard cultivars. Among accessions investigated, S-1 had the highest total phenolics and antioxidants (557.3 mg/100 g and 0.53 mmol/100 g) while P-4 had the lowest (307.3 mg/100 g and 0.22 mmol/100 g). The highest oleic acid content was determined in P-2 (87.16%); the lowest was in H-1 (71.24%). Linoleic acid ranged from 4.35% (P-1) to 18.06% (H-1). P-2 (3349 mg/kg and 2464 mg/kg, respectively) had the highest K and P contents. The highest Mg content was found in S-1 (1787 mg/kg). The highest value of Ca and Na was determined in P-1 (2701 mg/kg and 412 mg/kg, respectively). Principal component analysis revealed that the traits studied could effectively explain the variability among hazelnut genetic sources. First, three components explained about 60% of total variation. PC1 was related to arachidonic acid and most of the mineral elements (P, K, Mg, Ca, Fe, Mn, Zn, Cu, B, Cd, Ni, and S), and explained 27.6% of the total variation. PC2 explained 18.3% of the total variation, and was mainly related to oleic, linoleic, and linolenic acid, as well as Ca. PC3 was related to total phenolics, total flavonoids, antioxidant activity, and palmitic acid, and explained 14.5% of total variation. The oleic acid had a strong negative correlation with linoleic acid (−0.99 ***) and linolenic acid (−0.95 ***). A strong positive correlation was determined between antioxidant activity and total flavonoids (r = 0.95 ***). K content showed a strong positive correlation with P (r = 0.92 ***) and Mg (r = 0.82 ***) contents. A strong positive correlation was also determined between P and Mg (r = 0.91***). These findings revealed that many of the accessions investigated were a good source of fatty acids and bioactive compounds. As a conclusion, most accessions with superior nutritional content can be evaluated as genetic material for the development of new cultivars in hazelnut breeding programs.

Araştırmada elma atıklarının (yaprak, kabuk, posa) ultrason destekli su banyosunda 40 °C, %50 (333W) güç ve 2 saat sürede metanol ile alınan özütlerinin toplam fenolik madde miktarı (TFMM), antioksidan akivitesi, E. faecalis ve S. mutans inhibisyonu ve kolon kanser hücresi üzerine etkisi araştırılmıştır. Özütler içinde TFMM bakımından en yüksek değer yaprağa (104.72 mg/g) aittir. Atıkların antioksidan aktivitesi hem DPPH hem de ABTS yöntemiyle değerlendirilmiş ve her iki yöntemde de özütlerin yüksek antioksidan aktiviteye sahip olduğu bulunmuştur. Özütlerin patojenler üzerine antimikrobiyal aktivitesi olduğu bulunmuştur. Ayrıca; yaprak ve kabuk özütlerinin E. faecalis’e karşı posaya göre daha fazla inhibisyon potansiyeli olduğu görülmüştür. S. mutans üzerine en yüksek etkiyi ise yaprak özütleri göstermiştir. Çalışmada kullanılan kolon kanser (HT-29) hücresini özütlerin baskıladığı sonucuna varılmıştır. Sonuçlar, elma atıklarından ultrason ile alınan özütlerin patojen mikroorganizmalar ve kolon kanser hücresi üzerine inhibisyon aktivitesini ortaya koymuştur.
