Spondias purpurea L. plum is a source of antioxidant compounds. Nevertheless, once they are consumed and go through the digestive system, these compounds may undergo changes that modify their bioaccessibility. This study aimed to evaluate the effect of in vitro gastrointestinal digestion on the total content of carotenoids (TCC), ascorbic acid (AA), phenolic compounds (TPC), flavonoids (TFC), anthocyanins (TAC), and antioxidant capacity (ABTS, DPPH) of 12 plum Spondias purpurea L. ecotypes. The plum samples were subjected to the InfoGest in vitro digestion model. TCC, AA, TPC, TFC, TAC, ABTS, and DPPH were significantly different (p ≤ 0.05) in each in vitro digestion stage. The gastric stage released the highest content of AA (64.04–78.66%) and TAC (128.45–280.50%), whereas the intestinal stage released the highest content of TCC (11.31–34.20%), TPC (68.61–95.36%), and TFC (72.76–95.57%). Carotenoids were not identified in the gastric stage whilst anthocyanins were lost at the end of the intestinal digestion. At the gastric stage, AA presented a positive and high correlation with ABTS (r: 0.83) and DPPH (r: 0.84), while, in the intestinal stage, TPC and TFC presented positive and high correlation with ABTS (r ≥ 0.8) and DPPH (r ≥ 0.8), respectively.
Las enfermedades metabólicas, incluyendo la obesidad y la diabetes mellitus tipo 2, representan un grave problema de salud y mortalidad, en México. La Organización Mundial de la Salud (OMS) y otras asociaciones como la Federación internacional de la Diabetes (IDF) y el Programa Nacional de Educación para el Colesterol-Panel de Tratamiento para el Adulto III (NCEP-ATP III) definen el Síndrome Metabólico (SM), como la agrupación de alteraciones metabólicas que conllevan al desarrollo de obesidad, hipertensión y diabetes mellitus. El objetivo de este estudio fue desarrollar un modelo de SM en roedores CD1 utilizando una dieta hipercalórica y determinar las ventajas y/o desventajas comparado con otros modelos murinos. Se utilizaron ratones CD1 hembras y machos se dividieron en 2 grupos por género, un grupo control y otro grupo con dieta hipercalórica durante 10 semanas. Los resultados obtenidos mostraron que la dieta hipercalórica es eficiente para desarrollar las alteraciones metabólicas presentes en el SM, se observaron mejores resultados en los ratones macho, por lo que se sugiere la utilización en este género para evitar los cambios hormonales presentes en las hembras adultas
