Monoterpenes and triterpenes comprise the terpenes under investigation. Most of the attention is focused on two monoterpenes: limonene and perillyl alcohol.
Hydrocarbons mainly occurring in plants (e.g. oranges), used as alternative solvents for flux residue removal.
Unsaturated (double- bond- containing) hydrocarbons with composition C10H16; typically aromatic oils of natural origin.
Volatile hydrocarbons which are normal constituents of wood.
A group of unsaturated hydrocarbons present in plants. Terpenes consist of isoprene units, CH:C(CH)CH:CH. Diterpenes have four units, C 20 32.
Complex hydrocarbons (C10H16). Most volatile oils are mostly terpenes.
Highly unsaturated naturally occurring compounds in which the structural is isoprene.
Group of flavor chemicals forming the main component of hop oils.
Constituents that are the basis of a vast proportion of the volatile oils
Naturally occurring hydrocarbons, emitted by many trees and plants. They mostly have very strong smells and are responsible for the aromas of the vegetation in which they are found. Terpenes can be thought of as being built from units of isoprene, C5H8, joined together into chains and rings. Monoterpenes, formula C10H16, constitute the major emissions from conifers and fruit trees. Sesquiterpenes, formula C15H24, are commonly found in citrus trees. Terpenes are very reactive and may contribute to diminution of air quality in forested areas. The name comes from turpentine, a liquid consisting of several terpene compounds distilled from the resin of pine trees.
Strong, floral compounds influencing the aromas of especially riesling, gewürztraminer and the muscats; with bottle-age, terpenes often develop a pungent resinous oiliness.
