| titleOfInvention | Method for extracting and purifying cannabidiol from China hemp |
| abstract | The invention belongs to the technical field of plant component extraction and purification, and particularly relates to a method for extracting and purifying cannabidiol from hemp. The invention adopts supercritical CO 2 Extracting cannabidiol from hemp flowers and leaves in the mature period by an extraction technology, and further purifying the cannabidiol extract by using macroporous adsorption resin and a rapid purification system to obtain the cannabidiol product with the content of over 98 percent and no psychotoxic component tetrahydrocannabinol. The extraction process does not use a chemical organic solvent, is green and environment-friendly, and has low toxicity and high efficiency; the purification process reduces the loss of cannabidiol in the adsorption and elution process, effectively removes impurity components such as tetrahydrocannabinol and the like, reduces the use of organic reagents, reduces the purification cost and reduces the environmental pollution. The product has high yield and high purity, meets the development requirement of high value-added products of the hemp, particularly the market requirement of cannabidiol products as active ingredients in the hemp, and particularly has great application advantages in the pharmaceutical field. |
