Using GCxGC MS technology, we found that on average 40% of terpene content was not accounted for by the 40 standard terpenes used in cannabis testing labs. We have also detected other volatile compounds including alcohols, aldehydes, alkanes, aromatic and other hydrocarbons, esters, fatty acids, ketones and thiols. We will discuss the implications of this more comprehensive “volatilome” data including its significance in characterizing cannabis, distinguishing strains from each other, breeding for desired traits, improving quality and consistency of cannabis products, and even selecting better and safer processes and packaging.
