DefinitionThis section has been translated automatically.
Pinenes are monoterpene hydrocarbons, colourless liquids insoluble in water, readily soluble in ethanol, with the molecular formula C10H16. Alpha pinene is a main component (about 60%) of turpentine oil. Furthermore, pinenes, mostly alpha pinene (and beta pinene), are a component of numerous essential oils which were originally extracted from the balsam of the pine tree (pinus).
Alpha-pinene oxidizes easily in air, forming peroxides which quickly decompose into oxides. One oxidation product is ascaridol, a substance with high sensitizing potential.
A balsam is obtained from pine needles (lat. pinus), from which turpentine oil is distilled, which contains a high percentage of various substances. Pinene is distilled from turpentine oil. Furthermore the alpha - and beta-pinenes are found in myrtle, spruce needles, dill, fennel, coriander and caraway.
Alpha-pinene is used as a flavouring agent in the food industry. Pinenes are also found in technical products such as paints and oils.
