Abstract
A method of extracting pharmacologically active compounds from cannabis biomass is disclosed. The method comprises providing a raw biomass containing target compounds. Slurry is prepared by adding a solvent to the prepared biomass. In a preferred embodiment, the solvent may be a medium-chain triglyceride, such as coconut oil, or an edible and food-grade solvent or emulsifier used to standardize active compounds in pharmaceutical, nutraceutical, functional food, or cosmetic formulations. In some embodiments, the solvent may be a polyunsaturated fatty acid (PUFA), com oil, safflower oil, borage oil, flax oil, canola oil, cottonseed oil, soybean oil, olive oil, sunflower oil, monoglycerides, diglycerides, triglycerides, lecithin, limonene, essential oils of spices, herbs or other plants, fish oil, glycerol, glycols, or any other, or mixtures thereof. Various pharmacologically active compounds could be extracted from the slurry by processing in a continuous flow extractor. Successively, the solvent containing various pharmacologically active compounds may be separated from a spent biomass.
