Chemical compound

Vulpinic acid is a naturally occurring pulvinic acid derivative found in several lichen species, as well as some non-lichenized fungi. It was first isolated in 1925. It is bright yellow, and relatively toxic.

Occurrence in Lichen

Together with usnic acid and pinastric acid, vulpinic acid is secondary metabolite of the fungi. It is speculated that the substances are used as repellent for some herbivores. The substance showed also some activity against gram-positive bacteria.
