Chemische Eigenschaften
The pine (Pinus species) is one of the most important groups of plants called conifers. There are many different species, each having its own physical characteristics and specific growing requirements. Identifying features of different species include cone size and shape, and number of long, slender needles in each bundle. Generally, pines are more adaptable to Southern climate conditions than spruces and firs.
True pine oil consists of approximately 2% of the total distillable and extractable material from pine heartwood and stumpwood. The steam-distilled wood yields oil that is steam-distilled or fractionally distilled under vacuum. The lower boiling fractions yield the so-called wood turpentine. The steam-distilled chips are exhausted by extraction with a hydrocarbon solvent. The solvent is evaporated and the extract subjected to fractional distillation under reduced pressure. Again, the lighter fractions consist of turpentine, while the resinous residue consists of rosin. White or yellow pine oils are obtained after rectification. Pine tar oil can be prepared by destructive distillation of the wood and subsequent rectification. The wood is the only part used. Pine oil has a sweet, balsamic, anisic, pine-like odor.
Physikalische Eigenschaften
Pine oil, prepared by steam distillation and fractional rectification as described above, is a
colorless to pale-yellow liquid with a characteristic sweet, balsamic, pine-like odor. Its physical–chemical constants vary depending
on the source.
Essential oil composition
Its main constituents include sesquiterpene alcohols, ketones, terpineol, fenchyl alcohol, borneol, fenchone
and estragole.
