CBD: Main Compounds and Various Types Of Extraction Methods

The original name of the hemp plant is Cannabis Sativa L. plant. The plant is known for having hundreds of compounds in it. Cannabidiol is one of the essential compounds present in the hemp plant. It is also known as CBD, a popular substance among people throughout the world for its potential therapeutic health effects. People use it for many things, including as a sleep aid, preventing seizures, as appetite stimulants, pain relief, eczema, and psoriasis. The market is filled with various CBD-infused products, such as Capsules, CBD Oils, edibles, and Topicals. CBD is equally beneficial for dogs, and various CBD Oil for Dogs Canada is available on the market. So, let’s discuss the main compounds and various types of extraction methods of CBD, 

Main compounds in CBD:

Flavonoids: It is found in many plants such as vegetables, grains, and fruits. The cannabis plant contains over 20 flavonoids that might have anti-cancer, anti-inflammatory, and neuroprotective properties.

Cannabinoids: A cannabis plant contains over 100 cannabinoids, including CBD and tetrahydrocannabinol (THC). These two compounds are known for their psychoactive and therapeutic effects on cannabis products. THC might have an intoxicating effect.

Terpenes: Terpenes are known for providing aroma to a plant. The therapeutic effects of a cannabis product might come from terpenes. There are more than 150 terpenes in a cannabis plant.

What are the CBD extraction methods from the hemp plant?

Many extraction methods can apply to CBD extraction from a hemp plant. Every method is different and produces unique products and effects. All the CBD extract is in the form of concentration for human use. A CBD concentrate has more potential than raw cannabis. Here is the list of fundamental extraction processes:

Carbon Dioxide Extraction

It is also known as Superficial Fluid Extraction. Superficial CO2 has a liquid state and a gas state. During Carbon Dioxide Extraction, the superficial CO2 is used to separate CBD oil from the plant. There are three chambers in the machine for CO2 extraction. One chamber contains pressurized CO2, the other contains dried hemp material, and the third is for collecting the final CBD product. After that, the pressurized CO2 from the first chamber is pumped into the second chamber to change into superficial CO2. It creates CBD products and stores them in the third chamber.

Steam Distillation

This distillation process uses steam to extract CBD oil from the hemp plant. The machine for steam extraction has a condenser, an inlet and an outlet, a collection flask, and a boiler, and the steam travels through these chambers to extract raw plant materials and CBD oil. This process presents a mixture of CBD oil and water in the chamber.  After that, this mixture is distilled to separate water and oil. It is not the most efficient method of CBD extraction. The high temperature of steam might change the chemical properties of cannabinoids.

Vegetable Oil Extraction

Vegetable Oil Extraction is the safest, easiest, and most efficient extraction method. The raw material heat for 30-60 minutes at 248 F. This method uses to make the oldest method for oil extraction. After that, Olive oil mix with the raw material before heating it at 212 F. You can use sunflower oil, coconut oil, sweet almond oil, or MCT oil instead of olive oil.

Dry Ice Extraction

This extraction method is the most cost-effective and safest CBD extraction method as it uses dry ice for CBD extraction. To perform this method, you need a Plexiglas knife, CBD-rich cannabis, a clean plastic bucket, and around 3 pounds of dry ice. Additionally, three different size bubble mesh bags and three large glass jars for storage are needed.

Solvent Extraction

The working of Solvent extraction and steam distillation is similar. The steam distillation method uses water to extract oil, whereas Solvent extraction uses a solvent to separate oil from plant materials. The solvent Extraction method uses Hydrocarbons or natural solvents for CBD extraction. This product is a mixture of ethanol and extract, and the mixture is heated until the ethanol evaporates. But this method is expensive if we compare it with steam distillation.  This method is best for CBD edibles such as CBD Gummies Canada.

I hope you have got more details about the CBD compounds and extraction methods.
