Abietic acid (also known as abietinic acid or sylvic acid), a resin acid, is the primary irritant in pine wood and resin, isolated from rosin (via isomerization) and is the most abundant of several closely-related organic acids that constitute most of rosin, the solid portion of the oleoresin of coniferous trees. Its ester is called an abietate.
