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.
