- Semicontinuous Lixiviation Process for Compound Extraction from Cannabis sativa grown in Colombia Oscar Y. Buitrago-Suescún Miguel A. Santaella-Serrano Ingeniería lixiviation agroindustry Cannabis sativa solvent extraction semicontinuous process The extraction of compounds present in Cannabis sativa biomass from Colombian crops was studied using a semi-continuous lixiviation process. To this effect, three extraction stages were implemented, in which successive transfers were carried out at fixed times, seeking to emulate a continuous countercurrent process. In this way, the intention is to provide the Colombian agroindustry with an extraction method that is efficient and requires a lower initial investment than other techniques such as supercritical fluid extraction. Absolute ethanol was used as solvent, and constant temperature and stirring speed were applied. The obtained results indicate that, once the process is stabilized, extracted mass percentages (with respect to the total mass on a dry basis) of 10,5% at 40 °C and 9,5% at 19 °C are achieved, which are competitive compared to the 11,07% achieved through Soxhlet extraction. Besides, the proposed process is clearly a better alternative than a single-stage extraction method, through which it was possible to extract 5% of the mass. Five cannabinoids were identified in the obtained extract, and, with the proposed process, it was possible to extract 66% of cannabidiol present in the original biomass. 2022 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64379886002 https://www.redalyc.org/journal/643/64379886002/ https://www.redalyc.org/journal/643/64379886002/html/ https://www.redalyc.org/journal/643/64379886002/64379886002.epub https://www.redalyc.org/journal/643/64379886002/movil 10.15446/ing.investig.v42n2.91616 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.2 Vol.42
