Phytochemical profiles of four different honeysuckle varieties and four genotypes were studied. Polyphenols were identified by LC-PDA-QTOF/MS and quantified by UPLC-PDA and UPLC-FL. A total of 21 polyphenolic compounds found in the investigated fruit tissues were identified and presented as 6 anthocyanins, 6 flavan-3-ols, 4 phenolic acids, 3 flavanols, and 2 flavones. Among the identified compounds polymeric procyanidins and one luteolin derivative were quantified for the first time. Anthocyanins and flavan-3-ols were the major classes of honeysuckle polyphenols. The content of total polyphenols was between 775 mg (genotype ‘Klon 38’) and 2005 mg/100 g dry matter (cultivar ‘Duet’). The content of ascorbic acid ranged from 3.19 to 32.12 mg/100 g fresh matter for genotypes ‘Klon C’ and ‘Klon 44’, respectively. The content of polyphenolic compounds was highly correlated with the antioxidant activity. Some honeysuckle genotypes may be deemed interesting as applicable in human nutrition.
