Efecto de algunas fuentes de nitrógeno en la fermentación alcohólica de miel
2024Co-Authors: Quicazán, Martha Cecilia, Blanco Paz, Amaury José, Cuenca MarthaAbstract:El hidromiel es una bebida alcohólica obtenida mediante fermentación por levaduras de miel diluida. La producción de hidromiel es un proceso que consume mucho tiempo debido principalmente al bajo contenido de nitrógeno de la miel. Se evaluaron: sulfato de amonio, fosfato diácido de amonio, extracto de levadura y polen. Las fermentaciones se realizaron a 25°C usando Saccharomyces cerevisiae. El tiempo de fermentación se redujo en los mostos con adiciones de sulfato de amonio y extracto de levadura en comparación al mosto sin adición de fuentes de nitrógenoMead is a honey-derived beverage obtained by fermentation using yeast of diluted honey. Mead production is a time consuming process mainly due to low nutrient content of honey, which causes lack of uniformity and production of off-flavors in the final products. Ammonium sulphate, Dihydrogen Ammonium Phosphate, yeast extract and pollen were evaluated. Fermentations were conducted at 25°C by Saccharomyces cereviciae. Additions of Ammonium sulphate and yeast extract reduced fermentation length versus must without addition of nitrogen sources.Departamento Administrativo de Ciencia, Tecnología e Innovación [CO] ColcienciasUniversidad Nacional de Colombia1101-586-35750Desarrollo de un modelo productivo de bebidas fermentadas de miel como estrategia para generar valor en el ámbito característico de la apicultura en Colombian

determination of scutellarin in rat plasma by high performance liquid chromatography with ultraviolet detection
Journal of Chromatography B, 2003Co-Authors: Dafang Zhong, Binghua Yang, Xiaoyan ChenAbstract:A validated high-performance liquid chromatography method is described for the determination of scutellarin in rat plasma using a liquid–liquid extraction and ultraviolet (UV) absorbance detection. The separation used a Diamonsil ODS column ( mm i.d., 5 μm particle size) with an isocratic mobile phase consisting of methanol–acetonitrile–50 mM Dihydrogen Ammonium Phosphate buffer (22:15:63 (v/v/v), adjusted to pH 2.5 with 1 M phosphoric acid). The ultraviolet detector operated at 335 nm. Plasma samples were extracted with ethyl acetate after acidification. The extraction recovery of scutellarin ranged from 68.1 to 80.5%. High selectivity and a low quantitation limit (0.050 μg/ml) were achieved. The linear range was 0.050–12.5 μg/ml, correlation coefficient r=0.9981. The method has a good reproducibility, R.S.D. values were below 7.9% for within-day and between-day precision. The method is simple, rapid, and applicable to preliminary pharmacokinetic studies of scutellarin in rats.
