The CBD Extraction and Purification Process

CBD Extraction and Purification Process-min

The CBD extraction and purification process The extraction of Cannabis plant material and the purification of distinct fractions will be a step-wise process. Each step will result in a smaller amount of material in an increasingly purified form. We will produce pure CBD extract free of all of the possible contaminants in the plant (i.e. […]

Cannabis Concentrates

What are cannabis concentrates? Cannabis concentrates are the cannabinoids of the cannabis plant that have been extracted using one of the extraction methods described below. They are usually made by covering cannabis plant material with a solvent. After the solvent has extracted the cannabinoids from the plant material, the solvent is evaporated away leaving behind […]

Fractionation, Concentration & Downstram Processes

Stage 7. Fractionation and concentration of CBD from the cannabinoid-enriched material. There are a number of processes that could be applied to the cannabinoid-enriched material to isolate a CBD-enriched product. These include Supercritical Fluid (CO2) Extraction (SFE), Centrifugal Partition Chromatography (CPC), Molecular Distillation, Crystallization, etc. Ultimately, we are seeking to produce an purified extract that […]

Extract, Chlorophyll & Winterization

Stage 4. Primary extraction of the dried and milled Cannabis plant material. The dried and milled plant material will be extracted with the solvent of choice (e.g. ethanol) to generate a liquid extract of the Cannabis plant. This crude extract will contain the cannabinoids, the terpenes and the waxes (along with chlorophyll and other chemicals). […]

Extraction and purification of cannabinoids for the Medical Cannabis industry

Before developing the methods to extract cannabinoids from cannabis plant material, there are a number of steps that will need to be understood and implemented. Plant material with the desired chemical characteristics (e.g. the most appropriate cannabinoid profile) will need to be chosen. This may involve the selective breeding of premium plants or the purchase […]
