Cyclovariegatin is a pigment.[2] Its chemical name is 1,4-dihydro-2,7,8-trihydroxy-3-(3,4-dihydroxyphenyl)-l,4-dioxodibenzofuran. It is distinguishable by its UV-Vis spectra with maxima at 257, 296, and 430 nm. The variants cyclovariegatin-pentaacetate, cyclovariegatin-2,3',8-triacetate, and cyclovariegatin-2-acetate have also been described. It is derived from atromentin.[3] It has been isolated from the browned skin of Suillus grevillei var. badius, and becomes the pigment thelephoric acid.
