Abstract

Two new cyclopentenone derivatives, erigerenones A (1) and B (2), and a new cyclooctadienone derivative, erigerenone C (3), were isolated from the aerial parts of Erigeron philadelphicus L. Compound 2 was also isolated from the aerial parts of Erigeron annuus (L.) PERS. and Erigeron sumatrensis RETZ. The structures of 1—3 were elucidated on the basis of their spectral data.
