Diffractaic acid is a β-orcinol depside with the molecular formula C20H22O7, which is produced by lichens.[3][1][4] Diffractaic acid has cytotoxic, cytogenetic, oxidative, analgesic and antiviral effects.[4]

The foliose lichen species Punctelia diffractaica is named for the presence of this compound.[5]
