Extraction of Cannabinoids in Marijuana and Edibles by QuEChERS

Jul 06, 2017

Extraction of Cannabinoids in Marijuana and Edibles by QuEChERS

Medical marijuana has been legalized in multiple states across the USA. As a result, many testing labs are seeking fast and reliable analytical methods to determine the cannabinoid potency in marijuana and cannabis infused foods (more informally known as edibles). This application utilizes the advantages of the QuEChERS technique to extract cannabinoids in marijuana and cannabis containing foods. This is followed by either a dilution for marijuana samples or a solid phase extraction (SPE) cleanup for various complex food samples. This method results in clean extracts for instrumental detection.


1 gram homogenized food or 100 mg marijuana sample is hydrated with 10 mL reagent water for 30 min. The cannabinoids are then extracted into 10 mL of acetonitrile (MeCN) with the aid of EN15662 QuEChERS extraction salts for analyte partitioning and phase separation. After centrifugation the supernatant is either diluted or undergoes a secondary SPE cleanup before analysis.


Three representative cannabinoids, tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol (CBN) were selected for analysis in this study. The accuracy and precision obtained from spiked negative bread samples were excellent. The method was applied to 6 seized marijuana samples, and the cannabinoid contents and phenotypic indexes (THC/CBD and (THC+CBN)/CBD ratios) were reported.s (more informally known as edibles). This application utilizes the advantages of the QuEChERS technique to extract cannabinoids in marijuana and cannabis containing foods. This is followed by either a dilution for marijuana samples or a solid phase extraction (SPE) cleanup for various complex food samples. This method results in clean extracts for instrumental detection.
