Terpenes are colorless, although impure samples are often yellow. Boiling points scale with molecular size: terpenes, sesquiterpenes, and diterpenes respectively at 110, 160, and 220 °C. Being highly non-polar, they are insoluble in water. Being hydrocarbons, they are highly flammable and have low specific gravity (float on water).
Terpenoids contribute to the scent of eucalyptus, the flavors of cinnamon, cloves, and ginger, the yellow color in sunflowers, and the red color in tomatoes. [5] Well-known terpenoids include citral , menthol , camphor , salvinorin A in the plant Salvia divinorum , ginkgolide and bilobalide found in Ginkgo biloba and the cannabinoids found in ...
Santonin is a drug which was widely used in the past as an anthelminthic.It is a terpenoid and an organic compound consisting of colorless flat prisms, turning slightly yellow from the action of light and soluble in alcohol, chloroform and boiling water.

The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
Terpineol has a pleasant odor similar to lilac and is a common ingredient in perfumes, cosmetics, and flavors. α-Terpineol is one of the two most abundant aroma constituents of lapsang souchong tea; the α-terpineol originates in the pine smoke used to dry the tea.
These colors are also reflected in the Pan-African flag (black, red, and green) and the Ethiopian flag (green, gold, and red), which both have uplifting backgrounds that highlight the resilience ...
Tetraterpenes are terpenes consisting of eight isoprene units and have the molecular formula C 40 H 64. [1] Tetraterpenoids (including many carotenoids) are tetraterpenes that have been chemically modified, as indicated by the presence of oxygen-containing functional groups.
