- Extraction of Stevioside and Rebaudioside A from Stevia rebaudiana by percolation with ethanol-water solvents Liliana, Celaya Darío, Ferreyra Eugenio, Kolb Nicolás, Kolb Koslobsky Geología Yield Purity Percolation Crude Extract Ethanol Water The aim of this study was to analyze the optimum temperature and percentage of ethanol to extract steviol glycosides (Stevioside and Rebaudioside A) from stevia leaves in a percolation extractor. The experiments were performed in broad ranges of binary solvent (0-100 % ethanol) and temperature (30-70 °C) in order to investigate their effects on steviol glycosides recovery and purity. The optimal extraction conditions, which gave a best steviol glycosides extraction kinetic were 70 °C and 35% of ethanol. In addition, the optimal extraction condition giving maximum purity was 70% of ethanol between 30 and 70°C. 2022 artículo científico 0329-8922 https://www.redalyc.org/articulo.oa?id=382679632007 https://www.redalyc.org/journal/3826/382679632007/ https://www.redalyc.org/journal/3826/382679632007/html/ https://www.redalyc.org/journal/3826/382679632007/382679632007.epub https://www.redalyc.org/journal/3826/382679632007/movil 10.36995/j.recyt.2022.38.007 en http://www.redalyc.org/revista.oa?id=3826 Revista de Ciencia y Tecnología application/pdf Universidad Nacional de Misiones Revista de Ciencia y Tecnología (Argentina) Num.1 Vol.38
