✦ Synopsis

The title compound, C~14~H~10~O~5~, was isolated from Senecio cannabifolius Less var. integrifolius aqueous extract. The structure was elucidated on the basis of spectroscopic data, including MS, ^1^H NMR and ^13^C NMR, and the relative configuration was confirmed by X-ray crystallographic analysis. The benzofuran ring is almost coplanar with the furan ring [dihedral angle = 10.47 (15)°]. A chain is formed through supramolecular R
~2~
^2^(10) synthons and three-centre hydrogen bonds.
