- Determination of fructans in vegetative organs of Agave Offoyana (Asparagaceae) and its potential use as a prebiotic A.R. Hernández Montesinos D. Alfonso González Dayanna Coronado Acosta R. Reyes Fernández Daymara Rodríguez Alfonso Estudios Agrarios maguey Chromatography fructooligosaccharides Fructans are carbohydrates in which the links between fructose residues predominate. They are synthesized in approximately 15 % of angiosperms. These molecules have various applications in food and health, due to the lack of digestibility and their selective use by the beneficial intestinal microbiota in monogastric animals. The objective of this study was to determine, using chromatographic methods, the presence of fructans in vegetative organs of the endemic species Agave offoyana (maguey). Plants were collected in three different physiological states during two climatic periods. They were taken from the managed floristic reserve Tres Ceibas de Clavellina, in Matanzas province, Cuba. Samples were analyzed by different chromatographic methods. Thin layer chromatography showed the presence of fructans in stems and leaves, but not in roots. The accumulation was greater in stems. Both organs contain from the trisaccharide to molecules with a high degree of polymerization. The presence of the polysaccharide was greater in the leaves at the base than in the middle and shoot apex. There was an increase in the accumulation of fructans in the organ samples collected during the dry season. High-performance liquid chromatography confirmed the presence of fructooligosaccharides extracted from the stem. Results showed that Agave offoyana accumulates fructans in the stem, although they are also present in leaves. This Cuban species can be used to obtain fructans for human and animal feeding and health. 2024 artículo científico 0864-0408 https://www.redalyc.org/articulo.oa?id=653777768023 https://www.redalyc.org/journal/6537/653777768023/ https://www.redalyc.org/journal/6537/653777768023/html/ https://www.redalyc.org/journal/6537/653777768023/653777768023.epub https://www.redalyc.org/journal/6537/653777768023/movil en http://www.redalyc.org/revista.oa?id=6537 Cuban Journal of Agricultural Science application/pdf Instituto de Ciencia Animal Cuban Journal of Agricultural Science (Cuba) Vol.58
