Canadian golden oil is obtained from Solidago canadensis. It is a yellow oil of aromatic odour, of specific gravity 0 859 and optical rotation - 11 10. It consists of about 85 per cent, of terpenes, of which pinene, phellandrene, dipentene, and probably limonene are the constituents. There are also present bomeol, bornyl acetate, and cadinene. 

An oil distilled in Florida has been described, having an optical rotation of -H 17 50", and containing much phellandrene. Miller s more recent work makes the authenticity of this sample doubtful. The oil contains traces of aldehydes and ketones, and, probably, of salicylic acid The principal consrituenti of the oil is the dioaethyl ether of thymo-hydroqninone, Fhellandrene, bomeol, bornyl acetate, linalol and sabinene ( ) are present in the oil. 

Bomyl acetate [5655-61-8] is a characteristic component of most conifer oils. It has a camphoraceous, pine-needle-like odor. Both (+)-bomyl acetate [20347-65-3] and (-)-bomyl acetate form colorless crystals the racemate [36386-52-4] is a colorless liquid. Bornyl acetate is prepared by esterification of bomeol with acetic anhydride or via the process described under bomeol (see p. 61).

That the oil contains the following constituents, Z-a-pinene, d-a pinene, Z-limonene, Z-borneol, bornyl acetate and other esters of bomeol, Z-camphor, cineol, salicylic acid, aldehydes, formic, acetic, butyric ( ) and isovaleric acids, a non-volatile acid or lactone, and a blue constituent of high boiling-point. 

Scotch pine needle oil contains 50-97% monoterpene hydrocarbons composed mostly of a-pinene, with lesser amounts of 3-carene, dipentene, P-pinene, r/-limonene, a-terpi-nene, y-terpinene, cw-P-ocimene, myrcene, camphene, sabinene, terpinalene, and others. Other compounds reported present include bornyl acetate (3-3.5%), bomeol, 1,8-cineole, citral, terpineol, T-cadinol, T-muur-olol, a-cadinol, caryophyllene, chamazulene, butyric acid, valeric acid, caproic acid.
