| titleOfInvention | Methods for Obtaining Purified Cannabis Extracts and THCA Crystals |
| abstract | The present invention includes a method for obtaining a higher purity cannabinoid solvent extract from a plant which comprises cannabinoids and/or terpenes. A solvent extraction is performed on the optionally dried plant material, followed by a step of removing high molecular weight impurities by a cooling step. Following the cooling step, the precipitate is removed and a higher quality filtrate is obtained which contains higher levels of purity of cannabinoids and/or terpenes than the starting solvent extract. The methods of the invention also include a method for obtaining crystallized THCa, which comprises obtaining a filtrate by the methods disclosed herein, or obtaining a solvent extract, and allowing crystallization of the THCa to occur. The filtrate, crystallized THCa, and residual filtrate remaining after crystallization of THCa can be used as starting materials for products that include cannabinoids and/or terpenes. |
