Abstract
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), (1)H, (13)C, (1)H-(1)H gradient correlation spectroscopy (gCOSY), (1)H-(13)C gradient heteronuclear single quantum coherence (gHSQC), (1)H-(13)C gradient heteronuclear multiple quantum coherence (gHMQC), and (1)H-(13)C 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 (H(2)O(2)) scavenging assays, is also presented.
