Antioxidant property and characterization data of 1-o-galloylglycerol synthesized via enzymatic glycerolysis

This article provides comprehensive experimental data characterizing antioxidant activity, as well as chemical and physical properties of 1-o-galloylglycerol (GG), synthesized by enzymatic glycerolysis of propyl gallate (PG) using a food-grade lipase (Lipozyme® 435) [1]. GG was characterized by Fourier-transform infrared spectroscopy (FT-IR), 1H, 13C, 1H–1H gradient correlation spectroscopy (gCOSY), 1H–13C gradient heteronuclear single quantum coherence (gHSQC), 1H–13C gradient heteronuclear multiple quantum coherence (gHMQC), and 1H–13C gradient heteronuclear multiple bond correlation (gHMBC) nuclear magnetic resonance spectroscopies (NMR), and ultraviolet–visible spectrophotometry (UV–Vis). The antioxidant property of GG, which was evaluated through 1,1-diphenyl-2-picrylhydrazyl (DPPH•), 2,2′-azinobis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS•+), ferric reducing antioxidant power (FRAP), and hydrogen peroxide (H2O2) scavenging assays, is also presented. Keywords: 1-o-Galloylglycerol, Gallic acid derivatives, Lipase-catalyzed glycerolysis, Spectroscopic, Antioxidant activity
