"Quality control of cannabis inflorescence and oil products: Response factors for the cost-efficient determination of ten cannabinoids by HPLC"

The quality control (QC) of medicinal cannabis should include quantification of as many cannabinoids as practicable in a routine analytical laboratory, to accurately reflect the quality of the product. However, the cost and availability of some cannabinoid standards is an impediment to their routine use. This work seeks to overcome this obstacle by analyzing samples using relative retention times (RRT) and relative response factors (RRF), relative to cannabidiol (CBD) and cannabidiolic acid (CBDA) reference standards which are readily available. A high-performance liquid chromatography-photodiode array (HPLC-PDA) method was developed to quantify 10 cannabinoids ... (Full article...)
