ORGANİK OLARAK YETİŞTİRİLEN ÇİLEK VE YABANMERSİNİ MEYVELERİNİN FENOLİK BİLEŞEMİNİN İNCELENMESİ

Abstract

The present study aimed to investigate phenolic compounds of strawberry which is organically-grown in Bursa region and blueberry in Trabzon region. The phenolic acids and flavonoids were detected by RP-HPLC according to their retention times with the help of diode array detector at 280 nm, 320 nm and 360 nm. Investigated compounds were gallic acid, epigallocatechin, catechin, epicatechin, epicatechin gallate, 2 coumaric acid, 3 coumaric acid, 4 coumaric acid, chlorogenic acid, cafeic acid, neochlorogenic acid, trans resveratrol, ferulic acid, quercetin, kaempferol and myricetin. According to results it was determined that bluberry fruit contains high amounts of chlorogenic acid (644.25 mg/kg) and among the phenolic acids in strawberries, 4 coumaric acid is regarded as major phenolic compound (3.76 mg/kg). The highest level of myricetin compounds was measured in blueberry (14.41 mg/kg), on the contrary, myricetin was not identified in strawberry fruits but this fruit is especially rich in catechins (58.34 mg/kg).
