Abstract

Two new linear furanocoumarins, together with 13 known analogues, were isolated from the roots of Angelica apaensis. The structures of new compounds were elucidated by spectroscopic methods including extensive 1D and 2D NMR experiments, as well as high-resolution EI mass analysis. All furanocoumarins obtained were assayed for their cytotoxic ability against K562 and SMMC-7721 human tumor cell lines.
