Qualitative and quantitative detection method of one or more of cannabidiol, cannabidiolic acid and tetrahydrocannabinol

The invention relates to the technical field of detection, in particular to a qualitative and quantitative detection method of one or more of cannabidiol, cannabidiolic acid and tetrahydrocannabinol.The qualitative and quantitative detection method of one or more of the cannabidiol, the cannabidiolic acid and the tetrahydrocannabinol comprises the following steps that: ultrasound extraction is conducted on smashed hemp flower leaves through methyl alcohol, and a test solution is obtained; the test solution is separated and detected through high performance liquid chromatography, a moving phase of the high performance liquid chromatography is a mixture of acetic acid water solution and acetonitrile, and isocratic elution is conducted; and the content of one or more of the cannabidiol, thecannabidiolic acid and the tetrahydrocannabinol are detected through an external standard method. According to the qualitative and quantitative detection method of one or more of the cannabidiol, thecannabidiolic acid and the tetrahydrocannabinol, specific wave length and a moving phase are selected, the peak pattern is good, sensitivity is high, research is conveniently conducted, and qualitative and quantitative treatment of the cannabidiol, the cannabidiolic acid and the tetrahydrocannabinol can be detected quickly and accurately under treatment of the same sample.

The invention relates to a method for separating and purifying cannabinol from industrial hemp, and belongs to the technical field of chemistry. The method includes following steps: adding an ethanolsolution into the cannabinol crude product and stirring the solution to obtain a crude product ethanol solution; uniformly adding the crude ethanol solution into the activated macroporous resin column; carrying out normal-pressure elution on the macroporous resin by using a first ethanol solution to obtain a first eluent and first-time eluted macroporous resin; and performing normal-pressure elution on the macroporous resin subjected to primary elution by using a second ethanol solution to obtain a second eluent, adding a third ethanol solution into the second concentrated solution to obtain aconcentrated ethanol solution, and filtering and drying crystals to obtain cannabinol, of which the content is greater than or equal to 95%. The method has the beneficial effects that the high-puritycannabinol is obtained by separating the cannabinol according to the huge difference between the peak appearance time of the cannabinol in the reversed-phase column and other cannabinoid substances and then crystallizing the cannabinol; the method is simple to operate, low in cost and suitable for industrial production, and the problem of separation and purification of the cannabinol is solved.
