Abstract: Menyanthes trifoliataL. is a valuable medical plant found in Europe, North America, and Asia, which grows on peat bogs and swamps. It has long been used in folk medicine as a remedy for various ailments. This is the first report to demonstrate the protective antioxidant and anti-inflammatory properties of aqueous methanolic extracts derived from the aerial parts (MtAPV) and roots (MtRV) ofin vitrogrown plants on human umbilical vein endothelial cells (HUVECs). It describes the influence of the tested extracts on the expression of antioxidant (HO-1, NQO1,NRF2,kEAP1, andGCLC) and inflammation-related genes (IL-1α,IL-1β,IL-6,TNF-α, andIFN-γ) in cells stimulated with H2O2or LPS, respectively. In addition,M. trifoliataextracts were found to moderately affect the growth of certain bacterial and fungal pathogens, with the strongest antibacterial effect found againstPseudomonas aeruginosaandEnterococcus faecalis.M. trifoliataextracts demonstrated protective effects against mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) damage caused by ROS, decreasing the numbers of mtDNA lesions in theND1andND2genes and nDNA damage in theTP53andHPRT1genes and reducing cleavage in PARP1- andγ-H2A.X-positive cells. The root extract ofin vitro M. trifoliata(MtRV) appears to have better anti-inflammatory, antioxidant, antimicrobial, and protective properties than the extract from the aerial part (MtAPV). These differences in biological properties may result from the higher content of selected phenolic compounds and betulinic acid in the MtRV than in the MtAPV extract.
