US Patent 10946307 Extraction of cannabinoids, curcuminoids and ginsenosides

An example method for extracting phytochemical oil from plant parts includes freezing plant parts from at least one of Cannabis sativa, Curcuma longa, Panax ginseng, and Panax quinquefolius. The frozen plant parts are reduced to a plant powder, which is suspended in an aqueous buffer. The aqueous buffer containing the suspended plant powder is incubated with at least one pectinase and at least one cellulase. An aqueous phase of the incubated aqueous buffer is evaporated through steam heating to obtain a steam dried product. Phytochemical oil, which includes at least one of cannabinoids, curcuminoids, and ginsenosides, is extracted from the steam dried product.
