Composition Up to 80% monoterpene hydrocarbons, mainly a-pinene, myrcene, sabinene, limonene and P-pinene. As oxygenated compounds terpinene-4-ol (up to 10%) [125], bomeol, bomyl acetate, terpinyl acetate and a number of other compounds have been detected [126, 127, 128[. The composition of the oil strongly depends on the berry s degree of ripeness. The commercially available oils do, in the majority, not constitute pure berry oils, as needles and little twigs are included while harvesting and not removed before distillation. For latest reviews see Lawrence /7297 and Adams, who published a comprehensive work on the genus in 2004 [130[.
