Consalazinic acid is a chemical compound with the molecular formula {{chem2|C18H14O10}}. It is classified as a depsidone and is a secondary metabolite produced by a variety of lichens.
Consalazinic acid was first isolated from Parmotrema subisidiosum and described in 1980.{{cite journal | doi = 10.1016/S0031-9422(00)91070-7 | title = Structure of the β-orcinol depsidones, connorstictic and consalazinic acids | date = 1980 | last1 = O'Donovan | first1 = Donal G. | last2 = Roberts | first2 = George | last3 = Keogh | first3 = Myles F. | journal = Phytochemistry | volume = 19 | issue = 11 | pages = 2497–2499 | bibcode = 1980PChem..19.2497O }}{{cite journal | doi = 10.2307/3242974 | jstor = 3242974 | title = A Standardized TLC Analysis of β-Orcinol Depsidones | last1 = Culberson | first1 = Chicita F. | last2 = Culberson | first2 = William Louis | last3 = Johnson | first3 = Anita | journal = The Bryologist | date = 1981 | volume = 84 | issue = 1 | pages = 16–29 }} It has since been identified in many other lichens.{{cite journal | title = The Parmelia omphalodes (Ascomycetes) complex in Eastern Fennoscandia.
