摘　　要：Chemical investigation of Erigeron annus afforded two new eudesmenes, which were identified as 1β, 5α-dihydroxyeudesma-4(15)-en (1) and 1β, 7α-dihydroxyeudesma-4(15)-en (2). Their structures were established by spectroscopic methods including 2D NMR experiments.Chemical investigation of Erigeron annus afforded two new eudesmenes, which were identified as 1β, 5α-dihydroxyeudesma-4(15)-en (1) and 1β, 7α-dihydroxyeudesma-4(15)-en (2).
