               <mods:abstract>3r Premi Domènec Valero 2021The following project is focused at the development of a new method to exctract,&#xd;
concentrate, analyze and calculate the concentration of terpenes, cannabinoids and&#xd;
other natural components and metabolites of a Cannabis Sativa plant.&#xd;
Terpenes are the components that are in charge of the aromas and flavors of the&#xd;
plants (even if it has to be swallowed or smoked). Cannabinoids are the active&#xd;
ingredients that can have therapeutic, pharmacological and cosmetic uses.&#xd;
Most of this cannabinoids activates the endocannabinoid system through the&#xd;
Cannabinoid Receptor 1 (CB1) and Cannabinoid Receptor 2 (CB2), which are located&#xd;
at the Central Nervous System (CNS).&#xd;
The most commonly used cannabinoid is the Δ⁹-Tetrahydrocannabinol (THC), that&#xd;
when it couples with the CB1 and CB2, it has psychoactive effects, such as alteration&#xd;
of the perception, illusions or hallucinations; increased libido and even more.&#xd;
Not all the cannabinoids has this recreational uses, in fact, THC is the only one that&#xd;
has this purpose. Components such as Cannabidiol (CBD) or Cannabigerol (CBG) has&#xd;
a lot of medical and therapeutic uses, and is legal (or at least, aren’t strictly illegal).&#xd;
This therapeutic uses can go from anxiolytic or depressor, to improve the standard of&#xd;
living to patients with Parkinson or Multiple Sclerosis.&#xd;
To classify a C. Sativa plant as a therapeutic or for industrial uses, it should have a&#xd;
concentration of less than 0.2% of Δ⁹-THC. In order to know this, and that of another 30&#xd;
more, we will use the Solid/Liquid extraction and GC-MS techniques.Award-winning</mods:abstract>
