Abstract
A method for the isolation of delta-9-tetrahydrocannibinol (THC) from, Cannabis plant material, wherein delta-9-THC Acid and THC are separately obtained including the steps of extracting the Cannabis plant material, chelating delta-9-THC acid on alumina solid support from cannabis extracts rich in the acid washing of non-acid components of the extract with organic solvents and eluting of the delta-9-THC acid with strong polar solvents.
Claims5
