A new furobenzopyranone and other constituents from Anaphalis lactea.

Together with twenty-one known compounds, a new furobenzopyranone was isolated from the whole plant of Anaphalis lactea. Their structures were elucidated by spectroscopic methods MS, IR, UV, NMR, including 2D-NMR techniques. The anti-bacterial activity of compounds 1, 4-6, 14, 15 and the anti-tumor activity of compounds 4-6 were tested.
