Sažetak
Chokeberry (Aronia melanocarpa) fruits and its products are one of the richest sources of pholyphenols which may play important role in physiologic functions related to human health. The objective of this study was to evaluate, identify and quantify the content of pholyphenols, specifficaly phenolic acids (gallic, caffeic, p-coumaric, ellagic, chlorogenic) and flavonols (quercetin and kaempferol) using high performance liquid chromatography (HPLC) in two varieties of fresh chokeberry fruit and in different types of chokeberry products such as juices, powders, capsules, dried berries and teas. The results showed that there is a difference in amount of polyphenols between different product categories, and significant difference was also observed within the same product group (p≤0.05.). In all analysed samples the highest phenolic acid quantified was p-coumaric acid, and gallic acid was the lowest one. Berry juices from fresh chokeberry fruits, especially type Nero, had higher amount of p-coumaric acid (284.55±6.34 mg/L) compare to commercially available juices (195.48±3.05 mg/L). The same phenolic composition was observed within the rest of the products where capsules have the higher amount of phenolic acids, followed by powders, dried berries and teas (eg. p-coumaric 81.36 ; 79.76 ; 36.28 ; 28.81 mg/100 g dm respectively). According to flavonol amount, all observed products had higher values of quercetin compared to kaempferol. The results obtained in this study can be used for investigating of chokeberry and its commercial products influence on health and physiological functions.
