Description

Method of extracting high concentration cannabinoid oil from hemp seeds

The present invention relates to a method for extracting high-concentration cannabinoid oil from hemp seeds, and more particularly, to a method for extracting high-concentration cannabinoid (CBD) oil using only hemp seeds, a natural material from which the skin has been completely removed. it's about

Cannabinoids are a class of various compounds that activate cannabinoid receptors. Cannabinoids include endocannabinoids that are synthesized naturally in humans and animals. Phytocannabinoids are found in cannabis and other plants, and there are various other effects of cannabinoids.

Cannabidiol is a popular natural remedy used for many ailments. Better known as CBD, it is one of 104 chemicals known as cannabinoids found in the marijuana plant. CBD oil is derived from the cannabis plant but does not contain hallucinogenic THC.

Cannabis oil is known to be good for people who complain of chronic pain, inflammation, and emergency pain. It is also recommended for cancer patients when they need to get rid of the pain of chemotherapy and the disease itself. CBD is effective in reducing pain, promoting sleep, and reducing inflammation associated with diseases such as multiple sclerosis and rheumatoid arthritis.

Anxiety and depression are mental health disorders. Anxiety and depression are treated with medicines that can cause side effects such as drowsiness, insomnia, sexual dysfunction, and headaches. CBD oil is a safe treatment for post-traumatic stress disorder, insomnia and anxiety in children.

It helps reduce nausea, vomiting, pain and the side effects associated with cancer treatment and symptoms associated with cancer. According to research reports, the active ingredients in CBD oil can reduce the size of tumors and have cancer-preventing effects. In addition, the most studied diseases of CBD oil are the treatment of neurological diseases such as epilepsy and multiple sclerosis. It is also the part that works the most.

Studies have shown that CBD oil reduces pain and tremors, improving the quality of life and quality of sleep in people with Parkinson's disease. If you use CBD oil before bedtime and go to bed, you will get a better night's sleep.

Although THC is a psychoactive compound with long lasting side effects for users, CBD is not considered a psychotropic and is known to be safe for consumption by various routes of administration. The two compounds are usually found as mixtures in plant sources in various concentration ranges. For formulation into pharmaceutical compositions, cannabinoids are often extracted from plant sources by a variety of methods.

A further method used to obtain extraction of various compounds from various plant sources is super-critical CO2 extraction. In the CO2 extraction method, CO2 at super-critical conditions (ie high temperature and high pressure) is used for the extraction of cannabinoid species. Although relatively effective in extracting various compounds from plant sources, this technique is often more complex, time consuming and very expensive compared to liquid extraction. Additionally, the technique may simultaneously extract a variety of essential oils rather than selecting for a specific cannabinoid.

Although various methods exist for the extraction of cannabinoids, they all have the common disadvantages of low extraction yield and low (or no) selectivity. That is, the extraction methods known heretofore extract various species of cannabinoids from plant sources, often resulting in mixtures of CBD and THC in varying concentrations and ratios, preventing subsequent formulation and use of CBD in pharmaceutical compositions.

The present invention has been devised to solve the above problems, and it is to provide a method of extracting cannabinoid oil containing a high concentration of cannabinoids from hemp seed oil compressed and extracted using only hemp seeds, which are natural substances. there is this

In order to achieve the above object, the present invention comprises the steps of: (a) pressing the hemp seeds into an oil press; (b) collecting the oil extracted from the pressed hemp seeds in an oil container; (c) continuously supplying hemp seeds to the oil press of step (a) to continuously perform compression and (b) oil collection; and (d) separating the oil from water or impurities extracted during compression by closing the lid on the oil container in which the hemp seed oil was collected in step (c) and storing it at room temperature and in a dark place. A method for extracting cannabinoid oil is provided.

In addition, the method comprises the steps of (e) mixing the oil separated in step (d) with an alcohol of standard alcohol and stirring; (f) storing the stirred oil of step (e) at a cooling temperature in a refrigerator compartment, a freezer compartment or a jacketed filter reactor; (g) removing lipids, fats and waxes by filtering the oil stored in the cold storage of step (f); and (h) evaporating the alcohol by applying heat to the filtered oil of step (g).

In addition, the method is characterized in that it further comprises the step of (i) removing THC from the oil of step (h).

Hereinafter, the present invention will be described in more detail based on the following examples.

[Example]

Hemp seeds were pressed and fed to an oil press. While checking the oil container, when the container is full, the container is removed and the pressurized oil is transferred to a large glass bottle. The process was continuously carried out by continuously feeding the seeds into the hopper until all the seeds in a large quantity had been pressed.

The glass container containing the hemp seed oil collected by compression was closed, and the oil was separated from impurities such as water and other substances extracted during compression by placing it in a warm and dark place. After a day or so, separate the hemp seed oil from impurities such as water and store it in a separate container.

Since the extracted oil is crude oil, a refining process was separately added.

The extracted oil was mixed with standard alcohol and stirred vigorously until completely mixed. After that, keep it in a cool state for about 12 hours.

This cooling process can be carried out in a refrigerator compartment, a freezer compartment or a jacketed vessel or jacketed filter reactor. The use of recirculating chillers can cool jacketed vessels down to -20 °C.

The chilled oil crude oil was in a hazy state, and it was placed in an extraction vessel through filter paper to allow further filtration of impurities through a filtration process. Lipids, fats and waxes were removed through this filtration process.

The alcohol is evaporated by heating the oil to remove the alcohol from the filtered oil.

The solvent-free purified extract was dried on a tray in a vacuum oven to obtain a yellow to amber crystalline substance, which contained terpenes, THC and other cannabinoids, and thus THC was removed.

From this, it was possible to extract cannabinoid oil containing high concentration of CBD without THC.
