Any one of a series of isomeric hydrocarbons of pleasant aromatic odor, occurring especially in coniferous plants and represented by oil of turpentine, but including also certain hydrocarbons found in some essential oils.
Any of many homocyclic hydrocarbons with the empirical formula C10H16. Turpentine is mainly a mixture of terpenes. See hydrocarbon/surfactant blends.
A class of hydrocarbons characterised by (C5H8)_ and occurring in plant oils and resins.
an unsaturated hydrocarbon obtained from plants
Fraction of an essential oil consisting mainly of hydrocarbons, obtained as a byproduct from either concentration of distillation of the oil.
any of a large group of hydrocarbons found in essential oils, especially in conifers and other plants.
any of a few isomeric hydrocarbons; most volatile oils consist primarily of terpenes.
any of several isomeric hydrocarbons (C10H16); most volatile oils consist primarily of terpenes.
general name of hydrocarbons having the formula C10H16, related to isoprene, commonly occurring in many species of wood, and generally having a fragrant odor.
Complex Active Plant Constituents With A Carbon Ring Structure, Generally Highly Aromatic And Included In Essential Oils (Q.V.).
Terpenes are a large and varied class of hydrocarbons, produced primarily by a wide variety of plants, particularly conifers, though also by some insects such as swallowtail butterflies, which emit terpenes from their osmeterium. They are the major components of resin, and of turpentine produced from resin. The name "terpene" is derived from the word "turpentine".
