摘　　要：Two new butenolide derivatives, named as erigeracerin A and efigeracefin B, which are a pair of epimers, were isolated from Erigeron acer. Their structures were elucidated by spectroscopic analysis including 2D NMR and HR-ESI-MS.Two new butenolide derivatives, named as erigeracerin A and efigeracefin B, which are a pair of epimers, were isolated from Erigeron acer.
