Phytochemical investigation of the methanolic extract from the aerial parts of Agrimoniapilosa led to the isolation of three compounds, (-)-aromadendrin 3-O-β-D-glucopyranoside, desmethylagrimonolide 6-O-β-D-glucopyranoside, and 5,7-dihydroxy-2-propylchromone 7-O-β-D-glucopyranoside, together with nine known compounds, agrimonolide 6-O-glucoside, takanechromone C, astragalin, afzelin, tiliroside,
extracts of Agrimoniapilosa found to have anti-α-glucosidase and anti-inflammatory activities. Subsequent chemical study afforded a new phenylethyl isocoumarin glycoside (1) and eight known compounds (2-9). The structure of 1 was elucidated by comprehensive spectroscopic analysis and chemical transformations. All compounds showed modest α-glucosidase inhibitory activity (IC50 values ranging from 36.8 to
