Two novel bicoumarins named furobinordentatin (1) and furobiclausarin (3) have been isolated from the roots of Citrus yuko and C. hassaku, respectively. The structures were elucidated by single crystal X-ray analysis and/or spectroscopic studies as 1 and 3. The structural characteristic of these new bicoumarins is the presence of a tetrahydrofuran ring connecting two nordentatin or clausarin units.
