Abstract
A free radical scavenging activity guided fractionation of the polar extract from roots of Limonium brasiliense (Plumbaginaceae) led to the isolation of five active compounds including: myricetin 3-O-α-rhamnopyranoside (1), (-)-epigallocatechin 3-O-gallate (2), (-)-epigallocatechin (3), (+)-gallocatechin (4) and gallic acid (5). These and other chemical constituents are reported for the first time for this species. The characterization of these compounds was achieved by spectroscopic methods (1H NMR, 13C NMR and UV).
