Spectrophotometric and liquid chromatographic methods were used to determine anthocyanin and organic acid content and composition of commercial Finnish cranberries (Vaccinium oxycoccosL.). Solid-phase adsorbents were used in the fractionation of juice components prior to chromatographic determination. In the freshly prepared cranberry juice the total amount of anthocyanins was 7.7 mg/100 mL juice determined spectrophotometrically at 510 nm. The most abundant individual anthocyanins were cyanidin-3-galactoside (19.2%), cyanidin-3-arabinoside (23.1%), peonidin-3-galactoside (21.5%) and peonidin-3-arabinoside (14.1%), as determined by RP-HPLC.
