Study: What Is The Best Cannabis Oil Extraction Method?

Researchers Test Efficacy Of Various Cannabis Extract Solvents To Decide What Is The Best Cannabis Oil Extraction Method

By Drake Dorm

Cannabis extract medicine has been used for generations to help treat a variety of conditions, and its popularity has increased quite a bit in recent years. Much of this increased popularity can be traced to Rick Simpson‘s public campaign in favor of what he referred to as “hemp oil.”

“Ethanol and olive oil were determined to be the most effective, largely because of their ability to produce an extract with a high terpene content. Perhaps more importantly, both substances are safe for consumption.”
Last year, a group of researchers from the University of Siena (Italy) and Leiden University (Netherlands) completed a study comparing some of the most commonly used extraction solvents. Their results were published in the journal Cannabinoids.

Which Extraction Method Preserves Original Cannabis Terpenes?

In a previous analysis, we saw which extracts contain the most terpenes, in general. However, the type of extraction method that contains the most terpenes might not be preserving them in the same way they occur in the plant. Confused? Read on.

In the article Which Extract Has The Highest Terpenes, we pooled terpene profiles together and calculated which ones had the highest levels of cannabis terpenes. Budder and shatter (both BHO) tied for First Place, dry-sift non-solvent hash came in Second Place, live resin took Third Place, crumble followed with Fourth Place and rosin took Fifth Place. This ranking looks at sheer levels of terpenes, and does not qualitatively analyze what kinds of terpenes they had.

Here, we look at the ratio of the two general classes of terpenes present in cannabis: monoterpenes and sesquiterpenes. Monoterpenes (mainly myrcene, alpha-pinene, beta-pinene, limonene, linalool and terpinolene) are always present in higher amounts than sesquiterpenes (mainly caryophyllene, caryophyllene oxide and humulene), largely due to the fact that myrcene, a monoterpene, is present in such large quantities in all cannabis.
