ABSTRACT
The health-promoting activities of fruits are in the limelight in view of the growing risks posed by civilisational diseases and are connected with polyphenols. The present study examined bilberry, blueberry, blackcurrant, redcurrant, cherry and plum for their polyphenolic content and biological activities. The contents of total polyphenolic compounds and their subclasses were determined. Liquid chromatography high-resolution mass spectrometry was used to characterise the polyphenolic profiles. Small dark fruits’ antioxidant, anti-inflammatory, and anti-cholinesterase activities were also extensively determined. Significant qualitative and quantitative differences in the analysed fruits’ polyphenols composition and biological activities were demonstrated. The highest polyphenolic contents and antioxidant activities were established in blackcurrant fruit, but bilberry also had our attention due to an additional mild influence on antioxidant enzymes. The condensed tannin content in small dark fruits is developed. All tested fruits exhibit anti-inflammatory and anti-cholinesterase activities.
