Session 1: Best Practices and Advanced Topics

Cannabis Testing Best Practices: Making a Case for Understanding Fundamentals

Julie Kowalski, Lab Director, 1st Choice Labs

Cannabis testing has matured in recent years but there are still many opportunities to explore and improve as cannabis science evolves. This talk will make the case that understanding fundamentals of the techniques used is critical to establishing suitable methods that will not stumble and fail when implemented for daily use. And when methods do stumble, fundamental knowledge is key to successfully handling the (un)expected challenges. Primary understanding also allows one to improve upon and challenge current norms. Examples of applying basic analytical chemistry knowledge to design, improve, validate and troubleshoot cannabis methods will be discussed. 

Session 1: Best Practices and Advanced Topics

Characterizing xenobiotic hemp metabolites in the raw honey of Western honey bees (Apismellifera) by UHPLC-MS/MS

Edward A. Palumbo II, Senior R&D Scientist, Arcaea

Currently, there is a U.S patent granted for the process of administering high-CBD hemp extract to Western honey bees (Apis mellifera) through their food; the process results in raw honey infused with low milligram quantities of phytocannabinoids. The Western honey bee possesses several isoforms of CYP450 enzymes, CYP6 and CYP9, which are responsible for the oxidative metabolism of flavonoids, nicotine, and other xenobiotics consumed by bees. Based upon published pharmacokinetic studies, CBD is metabolized by CYP450 enzymes into both 7-COOH-CBD (MW: 344.44) and 7-OH-CBD (MW: 330.5).  The resulting honey possesses both primary and secondary CBD metabolites, 7-OH-CBD and 7-COOH-CBD, respectively, along with untransformed phytocannabinoids from the fed extract.
 

  • A reverse phase method was used to quantify the amount of each constituent on an Agilent 1290 UHPLC coupled to a 6470B Triple Quadrupole Mass Spectrometer (MS/MS).

  • A full phytocannabinoid method was developed to measure trace amounts of phytocannabinoid and phytocannabinoid metabolites in several raw honey samples.

  • Method Validation experiments, including spike recoveries, were performed using target compounds, and showed high specificity, precision, accuracy, and linearity.

  • The hemp or cannabis extract feed material chemotype is mirrored in the resulting honey based upon these analyses.

What is Next for Potency Testing? Part 2, Analytical Methodologies

Jean-Francois Roy, Mass Spectrometry Application Scientist, Agilent

As the cannabis market is expanding worldwide, many producers and testing labs are facing increased needs for accurate and highly robust potency testing. This market expansion comes with an expanded landscape of products to be tested for potency, which has prompted investigation on ways to improve and adapt analytical methodologies to these new products. This webcast will discuss various potential approaches to tackle these analytical challenges for potency testing.
