One new and three known coumarins were isolated from the $CHCl_3$ 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.
