Potency testing of up to twenty cannabinoids by liquid chromatography diode array detector with optional electrospray ionization time-of-flight mass spectrometry.
The growing popularity of Cannabis sativa L. and its widespread use for medical and recreational purposes have created an urgent demand of accurate and reliable analytical methods to identify and quantify a growing number of cannabinoids. To meet this demand, a liquid chromatography diode array detector (LC-DAD) method has been developed, validated, and applied in analysis of cannabinoids in nine samples of plant materials of marijuana, six samples of marijuana cigarettes, five samples of hemp flowers, one sample of hemp cigarette, and two samples of Δ
