Chemical structures of xanthyletin (top) and seselin

Pyranocoumarins are a class of chemical compounds that have a core structure that consists of a pyran ring fused to a coumarin. As phytochemicals, pyranocoumarins are uncommon and found mainly the plant families Apiaceae and Rutaceae.[1] For example, Citrus sinensis and Citrus limonia are sources of xanthyletin and seselin.[2]

In the biosyntheses of pyranocoumarins, the pyran ring is formed via the methylerythritol phosphate pathway and the coumarin is derived from the shikimate pathway.[2]
