METHOD OF PREPARING DELTA-9 TETRAHYDROCANNABINOL |
摘要 |
A method for the isolation of delta-9-tetrahydrocannibinol (THC) from Cannabis plant material, wherein delta-9-THC Acid and THC are separately obtained comprising 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 washing of non-acid components of the extract with organic solvents and eluting of the delta-9-THC acid with strong polar solvents. MThe method also includes a process by which to increase the THC content and decrease the weight of Cannabis extracts or residue from distillation of Cannabis extracts containing a low concentration of THC, comprising treatment of such materials with watermissible organic solvents followed by filtration and evaporation of the solvent to obtain the concentrated residue. |
