Water-based extraction and purification processes for cannabinoid acids |
| abstract |
The present invention relates to methods of extracting cannabinoid acids from cannabis plant material by combining the plant material with an aqueous solution having a high pH to solubilize cannabinoid acid anions, followed by precipitation of the cannabinoid acids at low pH and filtration. The method provides yields of up to 97%, while high pH purification of ethanol extracted oils yielded purities up to 86%. |
