What is the method for ethanol extraction?

Ethanol extraction is a method used to extract compounds, such as cannabinoids from plants, including cannabis.

It’s essential to exercise safety precautions during ethanol extraction due to the flammability of ethanol. Additionally, compliance with local regulations and standards, especially in industries like cannabis extraction, is crucial.


Material Preparation

  • Use high-quality plant material, such as cannabis buds.
  • Grind or chop the material to increase the extraction surface area.



  • Place the plant material in a container or extraction vessel.
  • Add ethanol (typically high-purity, food-grade ethanol) to the container, fully covering the plant material.
  • Allow the mixture to soak, facilitating the extraction of compounds from the plant into the ethanol.



Filter the mixture to separate the liquid (ethanol extract) from the plant material. This step removes solid plant material, leaving a solution containing extracted compounds.


Solvent Recovery (Evaporation)

  • Use evaporation methods to remove ethanol from the liquid, concentrating the extract.
  • This can be achieved using a rotary evaporator or a vacuum evaporation system.



  • If necessary, perform a decarboxylation step to remove carboxyl groups.
  • This may involve applying heat or other chemical treatments.



  • Conduct distillation to further purify the target compounds.
  • This helps separate and collect different volatile compounds.



  • Induce crystallization of the target compounds by lowering the temperature or employing other controlled conditions.
  • Crystallization can enhance the purity of the final product.
