Öz

Bu araştırmada 6 farklı elma suyu konsantresi (ESK) örneğinde fenolik bileşikler ve prosiyanidinler HPLC aygıtı ile belirlenmiştir. HPLC’e 280 ve 320 nm de 14 farklı fenolik bileşik ayrılmış ve teşhis edilmiştir. ESK’de fenolik bileşiklerden ortalama olarak; quercetin 133.9 mg/L, gallik asit 136.8 mg/L, kafeik asit 1.703 mg/L, prosiyanidin trimer 1.151 mg/L, klorogenik asit 176.9 mg/L, floridzin 138.7 mg/L, ferulik asit 2.691 mg/L; p-coumarik asit 4.345 mg/L ve epicatechin 1.839 mg/L düzeyinde belirlenmiştir. Elma suyu konsantrelerinde total sinnamik asit miktarı 66.64-297.90 mg/L ve total prosiyanidin miktarı ise 15.155-30.442 mg/L düzeyinde saptanmıştır.
