Tricyclic ring systems, where the furan ring is either linear or angularly linked to the coumarinum
The linear 7,6 - furanocoumarins are called psoralenes. They are photosensitising on which the PUVA therapy with 8-methoxypsoralen is based (see PUVA).
The most important representatives of the angular 7,8-furanocoumarins are pimpinellin (see below Pimpinellae Radix) and angelicin, which can be found in Apiaceae species, in Rutaceae and Fabaceae. Also the highly toxic and carcinogenic mycotoxins found in certain moulds (especially Aspergillus flavus), the aflatoxins have furanocoumarin structures.
Note(s)This section has been translated automatically.
Recent studies indicate that the furanocoumarins contained in citrus may increase the risk of non-melanocytic skin cancer due to phototoxic/sensitizing effects associated with UV radiation.
