Abstract Trifolium resupinatum L., Fabaceae, aqueous methanol leaf extract was selected to mitigate some obesity-associated risk factors validate the possibility of further developing herbal drugs. Chromatography and spectrophotometric techniques verified 14 phenolics, five which were first isolated from plant identified as 6''- O -acetyl ononin, genistin, daidzin, sissotrin, astragalin. Further phytochemical characterization performed via liquid chromatography-electrospray ionization-mass spectrometry assisted by a spectral similarity molecular network. In total, 81 metabolites tentatively annotated including 69 species-first dereplications. Two major isolates (formononetin pseudobaptigenin) along with investigated for an in vitro pancreatic lipase inhibition assay. They showed notable effects IC 50 values (µg/ml): 47.2 ± 1.1, 112.8 1.23, 471.32 0.8, respectively, incomparable orlistat (23.8 0.64).
