The invention relates to the field of biotechnology, in particular to a method for extracting cannabidiolic acid. The invention provides a method for extracting cannabidiolic acid, which comprises the following steps: after sterilizing industrial hemp, mixing with a strain whose preservation number is CGMCC: 1.3604, fermenting, adjusting the pH value to be alkaline, ultrasonically extracting, suction filtration, and collecting the extract , through organic solvent extraction and purification to obtain the cannabidiolic acid. The invention provides a method for extracting cannabidiolic acid, which makes up for the vacancy in the prior art, and most of the extraction methods for industrial hemp are based on chemical extraction methods. choose. Through the method provided by the present invention, the extracted cannabidiolic acid has higher purity. |
