There are several methods available for isolating CBDA from hemp. Among these are solvent extraction, ethanol extraction, chromatographic separation, and a combination of the three. These methods will vary in terms of the purity of the end product but will generally yield the same amount of CBDA.

Solvent extraction of CBDA from hemp involves using one of three types of hydrocarbons to extract CBDA from hemp plant materials. Alcohol, butane, or propane are all commonly used. Plant material is ground to a fine powder and soaked in the solvent. The solvent passes through the material, pulling out the cannabinoids, terpenes, and chlorophyll. The solvent is then evaporated.
Solvent extraction of CBDA from hemp is a simple process that involves the use of an equipment system. The system has three compartments: one for solid, pressurized CO2, the other for dried ground hemp plant material, and a third for the extracted material. The process begins by pumping a gas that has been preheated to a specific temperature. The CO2 gas then diffuses through the plant material. This heat releases carbon dioxide, which converts CBDA into therapeutic CBD.
The solvents used in solvent extraction are safe for human body oils and food—solvents like hexane help to retrieve maximum amounts of oil from organic material. On the other hand, water extraction is better for plant materials with high levels of natural oil.
Solvent extraction of CBDA from hemp is an economical way to extract CBDA. The chemical composition of the extracted CBDA depends on the genetic composition of the starting plant material. Previous research has evaluated the extraction parameters and optimized the recovery of significant phytocannabinoids. However, the impact of processing methodology on the full-spectrum composition of the extracted CBDA is not well understood. Commercial extraction approaches use alcoholic solvents, isopropyl alcohol, and supercritical CO2. While solvent extraction is the least expensive method of CBD extraction, it is often associated with trace contamination of organic solvents. Hydrocarbon solvents are toxic and should be avoided if possible.
Ethanol is a non-polar solvent that extracts cannabinoids and terpenes from cannabis plants. Temperature modulates its affinity for polar compounds such as cannabinoids and terpenoids. Cold ethanol will pick up cannabinoids and terpenes more efficiently than warm ethanol. Its low toxicity makes it an ideal solvent for small-scale cannabis processors.
Ethanol is a colourless, volatile solvent that has many advantages. It is commonly used as a solvent in the alcohol industry and is safe for use. It is also environmentally friendly. Ethanol extraction has a fast learning curve and can be used in large-scale operations.
During the ethanol extraction process, biomass is soaked in ethanol. The ethanol solution can be chilled or at room temperature. The solvent is evaporated, and the crude extract is refined to yield purified cannabinoids. Ethanol extraction equipment includes professional decarboxylation, large storage tanks, industrial filters, a gentle heating machine, storage tanks, and containers. The CBD is then infused into a carrier oil.
Ethanol has several advantages over CO2 extraction. Ethanol does not require a high-pressure environment and is cheaper to purchase than CO2. It can also produce a higher throughput than CO2.
Chromatographic separation of CBDA from hemp is an empathetic and accurate method for analyzing cannabinoids in hemp. Its advantages over other separation methods include greater specificity and rapidity. The method also eliminates the need for gradient elution, which is required for other separation methods. It can significantly reduce analysis time.
The two main chromatographic tools are GC and NMR. Both methods are effective and reproducible, but their sensitivity limits them to lipids and chlorophyll. Hazekamp and Choi developed the former method, and cannabinoid quantification was demonstrated by Casiraghi et al.
The new method uses a photodiode array detector and a reversed-phase HPLC method. It is optimized for the detection of cannabinoids, including CBDA and CBD. It is also used to quantify cannabinoids, including THCA and D9-THC. The solvents used in extraction are n-hexane and water.
CBDA is a significant constituent of the hemp plant. It is present in varying weight percentages in the plant and has therapeutic properties. However, before commercialization, it must be separated from other compounds. It isn’t easy to separate these compounds from hemp as many different compounds are present in the plant.
The results of this study show that the CBDA was the dominant cannabinoid in samples C2 and C5, while the CBDA had a relatively low percentage of CBD. This is in line with literature reports.
