| titleOfInvention | A kind of marijuana impurity removal method |
| abstract | The present application relates to the field of hemp impurity removal, and specifically discloses a cannabis impurity removal method. A method for removing impurities from cannabis includes the following steps: S1: pretreatment: drying and pulverizing cannabis flowers and leaves to obtain raw material powder; extracting the raw material powder with an ethanol solution to obtain a cannabis extract; S2: concentrating the cannabis extract Finally, carry out winterization treatment, filter to obtain filtrate, and concentrate the filtrate to extract; S3: decarboxylate the extract; S4: add an organic solvent to the decarboxylated extract for extraction, and filter to obtain Extracting liquid; S5: concentrating the extracting liquid to remove the organic solvent to obtain a cannabis extract; the organic solvent is at least one of alkanes or halogenated hydrocarbons. The preparation method of the present application can be used for cannabis impurity removal in cannabidiol extraction, and has the advantages of suitable cost and good impurity removal effect. |
