Abstract: Legumes are an interesting source of biologically valuable components. The aim of this study was to assess influence of the year on the content of phenolic compound, total polyphenol content and antioxidant activity of white lupine, chickpea and grasspea. The highest values of caffeic acid content were found in white lupine variety Los Palacios (734.64 mg.kg-1 DW), Solnecnyj (896.02 mg.kg-1 DW) in 2019. The content of trans-ferulic acid were the highest in cultivars Alban (19.34 mg.kg-1 DW), Sonecnyj (19.03 mg.kg-1 DW) in 2019. The highest content of myricetin were in selected genotypes Solnecnyj (25.86 mg.kg-1 DW) and Los Palacios (23.76 mg.kg-1 DW) in 2019. At the same time, statistical differences in the content of phenolic compounds in varieties of white lupine were evident. In the selected cultivars of chickpea and grass, the values of the content of phenolic compounds were below the detection limit. In 2019, the highest antioxidant activity and total content of polyphenols was found in all monitored types of legumes.
