3′-O-Caffeylerigeroside (pyromeconic acid 3-O-β-D-glucoside 3′-O-caffeyl ester) was obtained from the leaves of Erigeron annuus as a new pyromeconic acid derivative, and its structure was elucidated. Together with the γ-pyrone derivative, pyromeconic acid (3-hydroxy-4H-pyran-4-one) and its β-glucoside (erigeroside) were also isolated from the aerial parts of E. annuus. The siderophile activity of pyromeconic acid was also studied.
