Zhuang, Yuanhong published the artcilePreparation of functionalized pectin through acylation with alkyl gallates: Experiments coupled with density functional theory, COA of Formula: C10H12O5, the publication is International Journal of Biological Macromolecules (2022), 278-285, database is CAplus and MEDLINE.
The covalent grafting of alkyl gallates onto pectin using a lipase-catalyzed reaction in a tetrahydrofuran/aqueous medium process acylated pectin mols. with excellent antioxidant and antibacterial properties. The alkyl gallates including Me, Et, and Pr gallates were enzymically grafted onto pectin mol., in order to study the effect of alkyl gallates on the functional modification of pectin. The grafting mechanism was analyzed by UV-visible spectrum (UV-Vis), Fourier transform IR spectrum (FTIR), proton NMR (1HNMR), and d. functional theory (DFT). Results suggested that lipase grafted 4-OH of alkyl gallate onto pectin by catalyzing esterification in organic/aqueous solution, and the grafting rate was affected by the length of alkyl chain of the gallates mol. In vitro experiments, the acylated pectins exhibited stronger antioxidant activity in the DPPH test and β-carotene bleaching test and were found to have obvious antimicrobial performance against Escherichia coli and Staphylococcus aureus.
