Resumen
El potencial biosanitario de los polifenoles radica en su capacidad para modular el balance redox y losmecanismos implicados en el desarrollo de enfermedades crónicas no transmisibles.Objetivo: El objetivo de este estudio fue determinar la concentración de polifenoles totales en diferentesórganos murinos mediante el ensayo de las técnicas analíticas de Folin Ciocalteu (FC) y Fast Blue BB(FBBB).Método: ratones Balb/c hembras (n≥3) recibieron durante 15 días 100 mg/Kg/d de extracto de Lantanagrisebachii (LG), Aspidosperma quebracho-blanco (AQB) o Ilex paraguariensis (IP) y el grupo control(tratados con agua sin extracto). Las concentraciones de polifenoles se midieron en telencéfalo, diencéfalo,mesencéfalo, tallo encefálico, cerebelo, bazo, timo y tejido cardiopulmonar. Los resultados fueroncomparados por ANOVA seguido de la prueba de Tukey (p<0,05).Resultados: El método FBBB proporcionó estimaciones más altas que FC (4,5 veces en telencéfalo,8,4 en mesencéfalo, 5 en tallo encefálico, 7,2 en bazo, 68,5 en timo y 4 en tejido cardiopulmonar). Con respecto a los tratamientos, se halló con FBBB que el grupo tratado con AQB tenía un aumento del nivelde polifenoles en tallo encefálico (p<0,02). Con FBBB se detectó una disminución del contenido tímicode polifenoles tras el tratamiento con IP (p<0,005). Los cerebelos de los animales que recibieron IP y los telencéfalos de C mostraron diferencias significativas al ser analizados con FC (p<0,05, p<0,0035 respectivamente).Conclusiones: El método FBBB dio como resultado estimaciones más elevadas que FC, lo que podría estar relacionado con mayor especificidad de la técnica para reaccionar con compuestos fenólicos.
Biomedical potential of polyphenols lies in their ability to modulate redox balance and the mechanisms involved in the development of chronic noncommunicable diseases. Objective: The aim of this study was to determine the concentration of total polyphenols in different murine organs by assaying analytical techniques of Folin Ciocalteu (FC) and Fast Blue BB (FBBB). Method: Balb/c female mice (n≥3) received for 15 days 100 mg/kg/d of extract of Lantana grisebachii (LG), Aspidosperma quebracho-blanco (AQB) or Ilex paraguariensis (IP) and control group (treated with water without extract). Polyphenolic concentrations were measured in telencephalon, diencephalon, midbrain, brainstem, cerebellum, spleen, thymus and cardiopulmonary tissue by FC and FBBB methods. Results were compared by ANOVA followed by Tukey test (p<0.05). Results: FBBB method reported higher detections than FC (4.5 fold in telencephalon, 8.4 in midbrain, 5 in brainstem, 7.2 in spleen, 68.5 in thymus and 4 in cardiopulmonary tissue). Regarding the treatments, the group that received AQB showed to have increased polyphenolic bioavailability in brainstem (p<0.02). With FBBB, a decrease on thymic polyphenol content after treatment with IP was detected (p<0.005). In cerebellum of the groups treated with IP and telencephalon of the control group showed significant differences when these were analyzed with FC (p<0.05, p<0.0035 respectively). Conclusions: FBBB method showed higher estimations of polyphenolic bioavailability than FC, and this could be related to higher specificity of the technique to react with phenolic compounds.
