Abstract:
The invention relates to a method for the chromatographic purification of at least one cannabinoid compound, wherein the method comprises a main purification stage comprising the steps of: injecting an initial mixture comprising the at least one cannabinoid compound and one or more additional compounds onto a main stationary phase comprising silica particles, the silica particles comprising amino and/or diol groups; performing an elution with an elution solution, and collecting one or more elution fractions; and optionally, washing the main stationary phase with a washing solution and collecting one or more washing fractions; at least one of the elution fractions or washing fractions containing the at least one cannabinoid compound purified from the one or more additional compounds.
