Pinus palustris

The chemistry of fenchyl alcohol, Cj HjgO, must be regarded as in a somewhat unsettled state, as questions of isomerism arise which are as yet unsolved. It was ori nally prepared by Wallach by reducing the ketone fenchone, a natural constituent of several essential oils, by means of sodium. Later he obtained it in fairly large quantities as a byproduct in the preparation of fenchone-carboxylic acid, by passing a current of C(X through an ethereal solution of fenchone in the presence of sodium. Fenchyl alcohol has, so far, been found in one essential oil only, namely, that of the root wood of Pinus palustris.

The most abundant terpene in nature is a-pinene (119) which is industrially obtained by fractional distillation of turpentine [68]. (+)-a-Pinene occurs, for example, in oil from Pinus palustris Mill, at concentrations of up to 65% oil from Pinus pinaster Soland. and American oil from Pinus caribaea contain 70% and 70-80% resp. of the (-)-isomer [26].

C]-mevalonic acid (56a) in Pinus palustris or P. sylvestris showed that the Relabeling is predominantly at (4) . Namely, the C(4) of the monoterpene is derived from C(2) of mevalonic acid (56) rather than C(4) as had been assumed and therefore, the cyclopropane ring formation must be accompanied by a double bond migration if a-car-3-ene (61) is indeed dervied from a-terpinyl ion (62) or its biosynthetic equivalents.

Derivation By destructive distillation of pine wood, especially Pinus palustris. 

Derivation From pine trees, chiefly Pinus palustris and Pinus caribaea. (1) Gum rosin is the residue obtained after the distillation of turpentine oil from the oleoresin tapped from living trees. (2) Wood rosin is obtained by extracting pine stumps with naphtha and distilling off the volatile fraction. (3) Tail-oil rosin is a by-product of the fractionation of tall oil.

Discussing sap-stain on soft woods, Boyce says, Certain species are peculiarly susceptible to sap-stain. This is due both to toe character of toe wood and to the climatic conditions of the region where toe species growB. Western white pine, Bpruce, raid southern yellow pine, toe last-named wood including longleaf pine (Pinus palustris Mill.), shortleaf pine (P. echinata Mill.), and loblolly pine (P. tmda Linn.), are very subject to sap-stain, especially blue-stain, while true fir and cedar are not so easily affected. Douglas fir occupies an intermediate position.
