Olivetol, also known as 5-pentylresorcinl or 5-pentyl-1,3-benzenediol, is an organic compound found in certain

species of lichen; it is also a precursor in various syntheses.

Olivetol is a naturally occurring organic compound. It is found in certain species of lichens and can be readily extracted.

5-Pentylresorcino is also produced by a number of insects, either as a pheromone, repellent, or antiseptic.

The plant internally produces the related substance olivetolic acid (OLA), which was hypothesized that the plant,

in turn, utilizes to biosynthesize the psychoactive product.
