Abstract
|
|
|
|
The flower of Erigeron annuus L. was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH and H2O, 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 α-amyrenone, α-amyrin and β-amyrin. These three compounds were isolated for the first time from the flower of Erigeron annuus L.
