What Are Terpenes ?

What are Terpenes ?
Terpenes are found in the essential oils (flavinoids) of plants,
consisting of a large group of volatile unsaturated hydrocarbons.
Found commonly in conifers and citrus trees. In Cannabis,
terpenes are the oily compound, and the main building block
of resin that contribute to the flavor, scent and color of the oil.
The aeromatic nature of the Terpene give Cannabis its
unique smell. Terpenes are volatile molecules that evaporate
easily, and are oily compounds secreted by the plants
Trichomes. Cannabinoids and Terpenoids develop from THC
and Terpenes that infuse the plants flower tops,
share the same biochemical precursor (Geranyl
Pyrophosphate). Terpenes have the aroma, while Cannabinoids
are odorless.

In extraction, Terpenes can be extracted separately than the
Cannabinoids, and recombined at the end of the extraction
process. Terpenes are generally extracted in lower pressure
and no heat.

What about Terpenes during Decarboxylation ?
“ Besides cannabinoids, the cannabis plant contains a range of terpenes, which are the volatile compounds that give cannabis its distinct smell and may act synergistically with cannabinoids. Although preheating the plant material may release more of the known active (neutral) cannabinoids, it may simultaneously also cause loss by degradation or evaporation of components such as terpenes. Our tests were intended to better clarify the balance between desired decarboxylation and unwanted degradation. Unheated cannabis material was analyzed as a control.”

One thought on “What Are Terpenes ?

  1. Terpenes are the precious gift we smell and taste after our hard work. Locked up in the plants are powerful volatile chemicals that are easily released through natural processes as well as mechanical.
    The art of extraction comes from understanding that soft plants take absolute care to preserve all terpenes and medicinal properties. Colder temps throughout extraction will help maintain quality. Think of this if you want the seeds out of a pumpkin you carefully extract them not smash the pumpkin into bits and then try sort out the mess.
    This true for extracts. Once you have diluted your product with other plant matter besides what we really want the essential oils. These elements then require extensive purification to remove unwanted matter. Time and material are extremely valuable. Terpenes are also water based in large part so they can be dissolved by left over water in the wax after extraction ruining the entire run or several runs possibly.
