Abstract
An unprecedented alkylresorcinol glucoside, named citrifolin A, was isolated from the leaves of Eugenia citrifolia Poir. (Myrtaceae). Its structure was elucidated by nuclear magnetic resonance (NMR) spectroscopy in combination with high-resolution mass spectrometry (HRMS), and its absolute configuration was established by electronic circular dichroism (ECD) spectroscopy supported by density functional theory (DFT) calculations. The antioxidant potential of citrifolin A was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free-radical scavenging assays, in which the compound exhibited low activity.
