Title (EN) METHOD OF PREPARING DELTA-9-TETRAHYDROCANNABINOL
(FR) PREPARATION DE DELTA-9-TETRAHYDROCANNABINOL
Abstract: front page image
(EN)A method of preparing tetrahydrocannabinol using extraction of plant material with a non-polar solvent followed by vacuum distillation and collection of a constant boiling fraction. Additional distillation steps and chromatographic steps, including HPLC, reversed phase HPLC and flash chromatography, may be performed.
(FR)L'invention concerne un procédé de préparation de tétrahydrocannabinol, comprenant l'extraction de matière végétale au moyen d'un solvant non polaire suivie d'une distillation sous vide et de la récupération d'une fraction à point d'ébullition constant. Ce procédé peut en outre comprendre des étapes complémentaires de distillation et de chromatographie, notamment une CLHP, une CLHP en phases inversées et une chromatographie rapide sur colonne.
