ABSTRACT

Abstract Solidago species is a rich source of phenolic compounds with multi-pharmacological properties, particularly for the complementary treatment of various inflammatory diseases of the urinary tract. Phenolic acids and flavonoids are main compounds in the phytochemical profiles in Solidago spp. The aim of this study was to determine antioxidant profiles of leaves and inflorescences of four species as S. gigantea, S. canadensis, S. virgaurea, S.×niederederi from the wild populations in Lithuania. HPLC-ABTS assay coupled with UPLC-QTOF-MS was applied for the elucidation of antioxidant active compounds and determination of activity markers. Antioxidant profiles significantly vary within the species and plant part investigated. Chlorogenic acid and 3,5-dicaffeoylquinic acid were identified as the radical scavenging markers in leaves and inflorescences of Solidago species. The leaves of S. gigantea and S. virgaurea distinguished from other species by the highest amounts of radical scavengers. Solidago species is a promising source of fast acting high-capacity antioxidants.
