Polyphenolic Compounds and Antioxidant Activity in Berries of Four Russian Cultivars of Lonicera kamtschatica (Sevast.) Pojark

Nowadays increasing attention has been focused on polyphenolic compounds as the main representants of antioxidants in horticultural crops including fruits. The edible honeysuckle has an unique position among lesser known fruits due to its high level of antioxidants. In the present study we determined polyphenolic profile and antioxidant capacity of four Russian cultivars of edible honeysuckle including 'Gerda 25', 'Amfora', 'Morena', 'Lipnicka', which found together in a single location in Mendel University in Brno, The Czech Republic. Polyphenolic compounds were detected by high performance liquid chromatography coupled with electrochemical detector (HPLC-ED). The antioxidant capacity was measured by DPPH test. According to the results there were differences among cultivars in terms of polyphenolic content and antioxidant activity and Lonicera kamtschatica 'Gerda 25' were found to be possessed the highest content of phenolic compounds corresponding to the highest value of antioxidant activity.
