초록

A new chromone, (S)-5-hydroxy-2,8-bis(hydroxymethyl)-2-methyl-2H,6H-pyrano[3,2-g]chromen-6-one [named polymorphachromotriol, (5)], was isolated from the leaves Angelica poylmorpha along with seven known compounds hamaudol (1), isocopoletin (2), nodakenetin (3), 2 ',3 ' -dehydromarmesin (4), oxypeucedanin hydrate (6), norcimifugin (7), and cimifugin (8).
