Phenolic compounds from Syzygium jambos (Myrtaceae) exhibit distinct antioxidant and hepatoprotective activities in vivo

HPLC-PDA-MS/MS analysis of Syzygium jambos leaf extract allowed the identification of 17 secondary metabolites, including flavonol glycosides, flavonol di-glycosides, and flavones as well as ellagitannins and phenolic acids. The extract showed promising antioxidant activities in different experimental models. In Caenorhabditis elegans, the extract mediated a dose dependent survival rate and decreased the intracellular ROS level and HSP-16.2...
