Estabilidad físico-química del extracto hidroetanólico al 70 % de hojas de Spondias mombin L

The aim of the present work was to determine some quality parameters and to evaluate the stability of hydroethanolic to 70% extract of leaves of Spondias mombin L. (Anacardiaceae), stored at room temperature for one year. This specie is used traditionally for the treatment of diverse diseases because to its activity as antibacterial, anti-inflammatory and antioxidant. The leaves were collected in different stages of the cycle of life and it was used the maceration method. High-performance liquid chromatography (HPLC) analysis showed the presence of important phytoconstituents such as gallic acid and derivates and quercetin 3-O- glucosides. The parameters: organoleptic characteristics, pH, relative density, total solids, fixed solids, volatile solids, total phenolic and total flavonoids content were determined; the confidence intervals were established. The obtained data from the extract to the study of stability, related with these parameters, allow to assure stable behaviour during one year, from a physical-chemical standpoint.
