An original [[Gas chromatography|gas-chromatographic]] method has been developed for simultaneous determination of major [[terpene]]s and [[cannabinoid]]s in plant [[Sample (material)|samples]] and their [[Cannabis concentrate|extracts]]. The main issues to be addressed were not only the large differences in polarity and volatility between both groups of analytes, but also the need for an exhaustive [[decarboxylation]] of cannabinoid acidic forms. Sample preparation was minimized by avoiding any analyte derivatization. [[Acetone]] was found to be the most appropriate extraction [[solvent]]. Successful chromatographic separation was achieved by using a medium-polarity column. Limits of detection ranged from 120 to 260 ng/mL for terpenes and from 660 to 860 ng/mL for cannabinoids.

"Potency and safety analysis of hemp-derived delta-9 products: The hemp vs. cannabis demarcation problem"

Hemp-derived delta-9-tetrahydrocannabinol (Δ9-THC) products are freely available for sale across much of the USA, but the federal legislation allowing their sale places only minimal requirements on companies. Products must contain no more than 0.3% Δ9-THC by dry weight, but no limit is placed on overall dosage, and there is no requirement that products derived from hemp-based Δ9-THC be tested. However, some states—such as Colorado—specifically prohibit products created by “chemically modifying” a natural hemp component ... (Full article...)
