title: Polyphenolic compounds isolated from the leaves of Myrtus communis.
abstract: Four hydrolyzable tannins [oenothein B (1), eugeniflorin D(2) (2), and tellimagrandins I (3) and II (4)], two related polyphenolic compounds [gallic acid (5) and quinic acid 3,5-di-O-gallate (6)], and four myricetin glycosides [myricetins 3-O-beta-D-xyloside (7), 3-O-beta-D-galactoside (8), 3-O-beta-D-galactoside 6''-O-gallate (9), and 3-O-alpha-L-rhamnoside (10)] were isolated from the leaves of Myrtus communis. Antioxidant activities of the isolated compounds were evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay.
