Contribución al estudio fitoquímico de frutos de Syzygium Paniculatum (G.) y evaluación de su actividad antioxidante

Abstract

Syzygium paniculatum (G.), known as Bogota sabanera plum, is an ornamental plant. It is native of Australian shores and it have naturalized in some Latin American countries. Fruit is traditionally consumed in preparation of jellies, jams and syrups. The chemical study of fruits of Syzygium paniculatum has focused on analyzing the composition of the volatiles and some phenolic compounds, and these antiproliferative capacity against pancreatic cancer. This research aimed to determine the antioxidant capacity of four fruit extracts of different polarity and identifying the major secondary metabolites present in the methanol extract by analysis by high performance liquid chromatography coupled to mass spectrometer (HPLC-PDA- ESI-MS / MS), identifying esters of organic acids such as malic and quinic acid in downfield; while on medium and high field were identified polymers with phenol units and a compound of m / z 136, probably 4-ethylbenzene-1,2-diol. The results outline the sabanera plum fruit as a promising fruit with high antioxidant content.
