Abstract A new compound, 2,7,4a-trimethoxy-1,4,4a,8b-tetrahydrodibenzo-p-dioxin-4-one (1), was isolated from the aerial parts of the Hypericum reptans. The structure of the new compound was elucidated on the basis of extensive analysis of 1D and 2D NMR spectroscopic data and further confirmed by single-crystal X-ray diffraction.
