title: A new coumarin from the stem of Angelica dahurica.
abstract: One new and three known coumarins were isolated from the CHCl3 soluble fraction of Angelica dahurica stem. On the basis of spectral data, the structures of the isolated compounds were determined to be scopoletin, angelol I, angelol H and 6-[(1S), 2(R)-2, 3-dihydroxy-1-methoxy-3-methylbutyl]-7-methoxycoumarin; the latter being isolated for the first time from a plant source.
