Abstract
The flower of Erigeron annuus L. was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH and $H_2O$, successively. From the EtOAc fraction, three compounds were isolated through the repeated silica gel, ODS column and high performance liquid chromatographies. From the result of physico-chemical data including NMR, MS and IR, the chemical structures of the compounds were determined as ${\alpha}-amyrenone,\;{\alpha}-amyrin\;and\;{\beta}-amyrin$. These three compounds were isolated for the first time from the flower of Erigeron annuus L.
