Abstract: The present invention relates generally to improved methods for the extraction and isolation of cannabinoids from hemp. More particularly, the present invention relates to a series of extraction and isolation processes employed to selectively enhance recovery of non-psychoactive cannabinoids and the like, from cannabis materials and extracts, while removing undesirable naturally occurring components that may be present including colorants, carbohydrates, sugars and waxes, and the like, as well as contaminants that may be present in source materials including bactericides, fungicides, insecticides, plant growth regulators, environmental pollutants, and processing aids, and the like. The present invention further relates to an isolate obtained using a series of extraction and isolation processes that has extremely high cannabinoid content present in a stable, flowable liquid form that is essentially free of detectable levels of psychoactive cannabinol components.
