This study investigated the extraction of phenolic compounds from apple peel by ultrasound-assisted extraction (15, 30 and 45 min) and conventional extraction (15, 30, 45, 60, 75 and 90 min). The antioxidant capacity (DPPH), total phenolic content, total flavonoid content, and individual phenolic compounds of apple peel extracts were determined. HPLC analysis indicated that apple peel extracts had chlorogenic acid, rutin, catechin, epicatechin, procyanidin B1, procyanidin B2 and procyanidin C1. In the conventional method, the total phenolic content, total flavonoid content and antioxidant activity of apple peel extract in 90 min of conventional extraction was found as 1848.50 ±0.40 mg GAE/kg, 571.01 ±2.88 mgKA/kg and 9.70±0.00 mmol Trolox eq./g, respectively. In 45 min of the ultrasound-assisted extraction, total phenolic content, total flavonoid content and antioxidant activity of extracts were determined as 2021.83±65.69 mg GAE/kg, 532.66 ±2.43 mgKA/kg and 11.73 ±0.08 mmol Trolox eq./g respectively. The application of ultrasound-assisted extraction markedly decreased extraction time and improved the extraction efficiency compared with the conventional method.
Bu çalışmada, elma kabuğundan fenolik bileşiklerin ultrases destekli ekstraksiyon (15, 30 ve 45 dakika) ve konvansiyonel ekstraksiyon (15, 30, 45, 60, 75 ve 90 dakika) yöntemleri ile ekstrakte edilmesi araştırıldı. Elma kabuğu ekstraktlarının antioksidan kapasitesi (DPPH), toplam fenolik madde, toplam flavanoid madde ve bireysel fenolik içeriği belirlendi. İki farklı ekstraksiyon yöntemi ile elde edilen elma kabuk ekstraktlarında klorojenik asit, rutin, kateşin, epikateşin, prosiyanidin B1, prosiyanidin B2 ve prosiyanidin C1 tespit edildi. Konvansiyonel yöntemde 90 dakikalık ekstraksiyon sonunda toplam fenolik, toplam flavonoid ve antioksidan aktivite sırasıyla 1848.50 ±0.40 mg GAE/kg, 571.01 ±2.88 mgKA/kg ve 9.70 ±0.00 mmol Trolox eq./g olarak bulunurken 45 dakikalık ultrases destekli ekstraksiyonda toplam fenolik, toplam flavonoid ve antioksidan aktivite sırasıyla 2021.83 ±65.69 mg GAE/kg, 532.66 ±2.43 mgKA/kg ve 11.73 ±0.08 mmol Trolox eq./g olarak belirlendi. Konvansiyonel yöntemle karşılaştırıldığında, ultrases destekli ekstraksiyon uygulamasının elma kabuklarından fenolik madde ekstraksiyonunun süresini önemli ölçüde azalttığı ve ekstraksiyon verimliliğini arttırdığı tespit edildi.
