With an increasing appreciation for the unique pharmacological properties associated with distinct, individual [[cannabinoid]]s of ''[[Cannabis sativa]]'', there is demand for accurate and reliable quantification for a growing number of them. Although recent methods are based on highly selective [[chromatography]]–[[mass spectrometry]] technology, most are limited to a few cannabinoids, while relying on unnecessarily sophisticated and expensive [[High-performance liquid chromatography|ultra-high-performance liquid chromatography]] and [[tandem mass spectrometry]]. Here we report an optimized, simple extraction method followed by a reliable and simple high-performance liquid chromatography (HPLC) method for separation.

"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...)
