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.
鉴于文明病带来的风险日益增加，水果的促进健康活动成为焦点，并与多酚有关。本研究检测了越橘、蓝莓、黑加仑、红加仑、樱桃和李的多酚含量和生物活性。测定了总多酚化合物及其亚类的含量。采用液相色谱高分辨质谱法对多酚谱进行了表征。还广泛测定了小深色水果的抗氧化、抗炎和抗胆碱酯酶活性。研究表明，分析的水果的多酚组成和生物活性存在显著的定性和定量差异。黑加仑的多酚含量和抗氧化活性最高，但由于对抗氧化酶有额外的温和影响，越橘也引起了我们的注意。小深色水果中的缩合单宁含量得到了发展。所有测试的水果均具有抗炎和抗胆碱酯酶活性。
