Choosing the right extraction method for a given ingredient or product requires consideration of the characteristics of each available method. There are several. Oct 30, Which extraction method is best for your cannabis company? Hydrocarbon extraction typically refers to using butane or propane as a solvent that’s passed through the raw cannabis matter to collect cannabinoids and terpenes. Ethanol extraction is conducted by soaking raw cannabis. Jul 25, By Rick Scarpello, CEO of Medically Correct. Let's discuss cannabis extraction methods with facts and not religion. I'm pro-faith, but let's call it.
Right Method the Choosing Extraction
This kind of extract is also known as shatter, which is a clear material that typically includes THC, CBD and other chemical components, including terpenes. To really make shatter, which is a hard version of butane hash oil, terpene content must be kept low or it works like a solvent that makes the extract soft.
The right starting sample can help to reduce the terpenes present in the final product, such as by starting with cured flowers. On the other hand, the butane hash oil can be heated to remove terpenes after extraction as they are more volatile than cannabinoids like THC and CBD. Cannabis alcohol extraction Several common forms of cannabis extraction rely on a solvent, such as alcohol. In brief, the cannabis soaks in alcohol, usually ethanol, the plant material is then removed, the liquid filtered, and the alcohol is removed with some form of evaporation.
One of the biggest challenges is the inherent polarity of solvents like ethanol—meaning it has a propensity to mix with water and dissolve water-soluble molecules like chlorophyll. Removing the chlorophyll from the extract is important as it produces an undesirable, bitter flavor.
A cannabis tincture created using alcohol-based extraction. This method can be performed at atmospheric pressure, but the temperature is carefully controlled, especially during evaporation. This process can also take time and must be done carefully to avoid danger as ethanol is highly inflammable. One of the biggest benefits of this form of extraction is that there is no risk of leaving toxic residual chemicals in the final cannabis extract and, it enables the co-extraction of all compounds of interest, chiefly cannabinoids and terpenoids.

A selection of supercritical CO 2 extraction equipment available from Eden Labs. Also, some of the extraction methods used in that study estimated a lower abundance of certain genera. These issues can be solved only by experimental testing. The study presented here allows to compare certain features of the extracted DNA, and more importantly, the final microbial population structure, based on the DNA recovered with the use of different extraction kits.
Although in this particular case, the C1 or C8 kits seem to significantly stand out from other tested kits, their utility for different soil samples should be considered and experimentally verified for each sample. It is important to indicate that the soil sample used in this study was very unusual.
Currently, this area is subjected to reclamation, and was covered with sludge from wastewater treatment plants, which is characterized by the presence of heavy metals, such as copper, zinc, cadmium, lead, chromium, and nickel; the area is also covered with a vegetation. It resulted in unusual composition of various heavy metals and mineral compounds. Thus, the results obtained in current study should be treated with caution, when other type of soil is to be investigated. As tested kits might be optimized using different type of soil samples, the kits which showed low performance in our study may show excellent DNA extraction efficiency when used on less complex samples.
Based on those facts, we propose that for a single soil sample, as well as for other heterogeneous environmental samples, many DNA extraction kits should be tested at an early stage of the study. Later, based on the amount and quality of the obtained DNA, and also on diversity of the sequences and diversity indexes, as well as reproducibility of the kit extractions, the most suitable protocol should be selected for further analysis.
In some cases, in order to improve the analysis, the tests and comparisons of various DNA extraction protocols should be pursued throughout the whole analysis, not only at the early stage of establishing the amount and quality of the recovered DNA. However, this involves an increase in the project costs and is much more time consuming, but when selecting a particular DNA extraction method, one should be aware of its limitations and alternatives.
Nonetheless, it could improve the data analysis and thus could be a useful approach in order to present the closest assessment to the actual structure of the microbial population. However, it should be noted that in such studies the view of the final microbial community structure also depends on the sequencing technology and bioinformatics tools used, which were beyond consideration in this study.

Another extraction method that is also relatively popular is the Olive Oil extraction method. The process is much more straightforward than a Supercritical CO2 extraction. The hemp plant is decarboxylated and then placed in olive oil, which is then heated to a certain degree to extract that Cannabidiol and other Cannabinoid contents from the plant. This is a safer procedure and is also more affordable, resulting in a product that is priced lower than one where a Supercritical CO2 extraction method was used.
This method is very similar to the extraction method where Olive Oil is used. It is also more common in commercial productions of CBD oil since it yields a better rate of CBD oil that can be used in the manufacturing of commercial products.
The plant is also first decarboxylated and then heated in Ethanol to extract that Cannabinoids found in the plant into the solution it is being heated in. Solvent extraction methods offer a cheaper alternative to the popular Supercritical CO2 extraction method but also holds some risks that you need to be wary of.
Technically, the Ethanol extraction method is categorized as a Solvent Cannabidiol Extraction method. There are other substances, including Butane, which is also used as Solvents to extract Cannabinoids from hemp and other Cannabis plants.
Products that contain CBD oil extracted through a Solvent Extraction process are usually much cheaper than those that have been extracted through the Supercritical CO2 method, but these oils are not as pure or safe in comparison. There are several risks involved in the process, such as the possibility that certain toxins may be left behind in the oil post-extraction.
