Terpene
Definition:
(n.) 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.
Example Sentences:
(1) Cyclic terpenes were selected from the chemical classes of hydrocarbons (e.g., alpha-pinene), alcohols (e.g., alpha-terpineol), ketones (e.g., carvone), and oxides (e.g., 1.8-cineole, ascaridole).
(2) From the unsaponifiable fraction (63 g) of linseed oil (25 kg), two terpenic alcohols were isolated by alumina column, thin-layer, and gas-liquid chromatography.
