| Description | This compound belongs to the class of organic compounds known as coumestans. These are polycyclic aromatic compounds containing a coumestan moiety, which consists of a benzoxole fused to a chromen-2-one to form 1-Benzoxolo[3,2-c]chromen-6-one. They are oxidation products of pterocarpan. |
