Abstract A new flavone glycoside, eupatilin 7-O-β-d-glucopyranoside (1) and a new flavone, 5,6,2′,4′-tetrahydroxy-7,5′-dimethoxyflavone (2), were isolated from Artemisia argyi. Their structures were unambiguously elucidated by extensive spectroscopic analysis. Both flavonoids were evaluated for in vitro anticoagulation activities. Compound 1 significantly extended thrombin time. Compound 2 had obvious effect in increasing prothrombin time.
