Extraction of essential oils of cannabis sativa varieties punto rojo and mango biche

Abstract

This research is intended to idenfify the process and optimum solvent for the extraction of sativa cannabis oil from the punto rojo and mango biche varieties. There are multiple techniques used for their extraction. Their key principle is the use of an extractor agent, which may be petroleum ether, ethyl alcohol / ethanol, water, among others. When in contact with the solid material, the extractor agent allows the solutes, that is, the phyto-cannabinoids, to be transferred to the solvent to be then separated. In this way the essential oils are obtained. The aims of the stuy are (1) to identify the existing processes for extraction of essential oils and the description of the different solvents; (2) determine the advantages and disadvantages of each of these; (3) make the selection of the most appropriate method; and (4) put it into practice and perform laboratory tests to determine the percentage of Tetrahydrocannabinol (THC) and Cannabidiol (CBD).
