| "Commercial turpentine may be roughly divided into two general types, that produced from gum and that produced from wood. Gum turpentine is distilled from the oleoresin of the living tree. In the United States it is is obtained principally from two species, longleaf pine and slash pine (Pinus palustris Mill. and Pinus caribea Morel.)." \\ | "Commercial turpentine may be roughly divided into two general types, that produced from gum and that produced from wood.

| | "'American turpentine' of the world trade is a mixture of turpentine of P. palustris and P. caribaea. Composed samples of turpentines of the two pines differ in that P. caribaea turpentine is laevorotatory because of a predominance of l-α-pinene; while turpentine of P. palustris is dextrorotatory on account of a predominance of d-α-pinene." \\ |

| "Turpentine is a natural oleo-resin, formed as a physiological product in the trunks of Pinus palustris and other species of Pinus (see also Larch Turpentine)... The turpentine consists of an essential oil, known as turpentine oil, and a resinous substance known as Rosin. The latter is a mixture of various resin-acids and resin-acid anhydrides, commercially known as Abietic Acid. By steam distillation of turpentine, about one-sixth of the weight of the natural oleorsin distils with the water as turpentine oil while five-sixth are left as rosin...Derivatives of rosin are used as fixatives... Abietol (a mixture of dihydro- and tetrahydro abietic acid), Abalyn (methyl abietate), Hercolyn (methyl dihydroabietate), Hercolyn D (same, but distilled and deodorized)." \\ | "Turpentine is a natural oleo-resin, formed as a physiological product in the trunks of Pinus palustris and other species of Pinus (see also Larch Turpentine)...
