Bu çalışmada Türkiye’nin Antalya ilinde yetiştirilen yirmialtı çeşit pikan cevizinin toplam fenolik, flavonoid miktarı ve antioksidan aktiviteleri belirlenmesi amaçlanmıştır. Pikan cevizi çeşitlerinin toplam fenolik ve flavonoid miktarları sırasıyla 372.94-1271.92 mg GAE/100 g ve 137.03-575.32 mg CE/100 g olarak belirlenmiştir. Shoshoni çeşidinin en yüksek toplam fenolik içeriğine sahip olduğu, bunu sırasıyla Wichita (1134.07 mg GAE/100 g), Mahan (1100.21 mg GAE/100 g) ve Moneymaker (1085.12 mg GAE/100 g) çeşitlerinin izlediği belirlenmiştir. En yüksek toplam flavonoid miktarı ise Wichita çeşidinde belirlenmiş, bunu sırasıyla Mahan (385.83 mg CE/100 g), Cheroke (335.94 mg CE/100 g) ve Big Z (344.45 mg CE/100 g) çeşitleri takip etmiştir. Çeşitler arasında en yüksek fenolik içeriğine sahip Shoshoni çeşidi, aynı zamanda en yüksek DPPH radikali giderme aktivitesi (3.50 mg/mL) göstermiştir. FRAP değerleri açısından, en yüksek değerler sırasıyla Wichita ( 147.93 mmol TE/g), Mahan (112.10 mmol TE/g), Harris Super (99.90 mmol TE/g) ve Shoshoni (99.17 mmol TE/g) çeşitlerinde belirlenmiştir.
This study aims to determine the total phenolic, flavonoid and antioxidant activity of twenty-six species of pikan cabbage grown in the province of Antalya of Turkey. The total phenolic and flavonoid amounts of coconut varieties were determined as 372.94-1271.92 mg GAE/100 g and 137.03-575.32 mg CE/100 g respectively. The shoshoni variety has the highest total phenolic content, followed by Wichita (1134.07 mg GAE/100 g), Mahan (1100.21 mg GAE/100 g) and Moneymaker (1085.12 mg GAE/100 g) respectively. The highest total amount of flavonoids was determined in the Wichita variety, followed by Mahan (385.83 mg CE/100 g), Cheroke (335.94 mg CE/100 g) and Big Z (344.45 mg CE/100 g) varieties respectively. The Shoshoni variety with the highest phenolic content among the varieties also showed the highest DPPH radical elimination activity (3.50 mg/mL). In terms of FRAP values, the highest values were determined in the varieties Wichita (147.93 mmol TE/g), Mahan (112.10 mmol TE/g), Harris Super (99.90 mmol TE/g) and Shoshoni (99.17 mmol TE/g) respectively.
In this study, it was aimed to determine the total phenolic, flavonoid contents and antioxidant activities of twenty-six cultivars of pecan grown in Antalya province. According to the research results, the total phenolic and flavonoid contents of pecan cultivars were determined as 372-1271.92 mg GAE/100 g and 137.03-575.32 mg CE/100 g, respectively. It was determined that Shoshoni cultivar had the highest total phenolic content, followed by Wichita (1134.07 mg GAE/100 g), Mahan (1100.21 mg GAE/100 g) and Moneymaker (1085.12 mg GAE/100 g), respectively. On the other hand, the highest total flavonoid content was determined in Wichita cultivar, followed by Mahan (385.83 mg CE / 100 g), Cheroke (335.94 mg CE/100 g) and Big Z (344.45 mg CE/100 g), respectively. Among cultivars, Shoshoni cultivar with the highest content of total phenolic showed also the highest DPPH radical scavenging activity (3.50 mg/mL). In terms of FRAP values, the highest values were determined in Wichita (147.93 mmol TE/g), Mahan (112.10 mmol TE/g), Harris Super (99.90 mmol TE/g) and Shoshoni (99.17 mmol TE/g) cultivars, respectively.
