Cover Story: Cannabidiol is the major non-psychoactive cannabinoid in Cannabis and has several positive pharmacological effects. Due to increasing interest over the past few years, numerous cannabidiol cosmetics have appeared on the free market. Therefore, it is of utmost importance to develop reliable and rigid quantification methods to control ingredient concentrations and guarantee high-quality products. One suitable procedure was developed in this study. A novel, highly apolar and pure room temperature ionic liquid was synthesized and applied as extracting agent for liquid-phase microextraction of cannabidiol from cosmetics. Separation and quantification were accomplished via high-performance liquid chromatography in conjunction with ultraviolet detection. View this paper.
