Pimaric is a resin acid, so part of the tree resin. Pimaric belongs to the group of tricyclic diterpene carboxylic acids, and thus consists of four isoprene units.

Extraction

When heated pine resins in closed boilers above 100 ° C, so distilled water and turpentine over, while remaining in the boiler melt on cooling to a glassy mass - called rosin - solidifies. Pimaric is a part of this mass.
