2-L-天冬氨酸-2-脱氧-D-葡萄糖的合成及热裂解分析
Synthesis and Pyrolysis of 2-L-Aspartic Acid-2-Deoxy-D-Glucose
摘要
Abstract
2-L-Aspartic acid-2-deoxy-D-glucose was synthesized from D-fructose and L-aspartic acid monopotassium salt,and it was characterized by Fourier transform infrared spectroscopy,1H nuclear magnetic resonance (NMR),13C NMR and high resolution mass spectroscopy.The thermogravimetdc behavior,thermal pyrolysis behavior and antioxidant activity of 2-L-aspartic acid-2-deoxy-D-glucose was investigated using thermo gravimetry-derivative thermo gravimetry (TG-DTG),on-line pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS),and 1-diphenyl-2-picrylhydrazyl (DPPH) scavenging and reducing capacity assays,respectively.The results showed that the synthetic product was confirmed to be the target compound.The target compound has a pyrolysis temperature of 187.8 ℃ and a total weight loss of 91.26％ at 700 ℃.The number of pyrolysis products from the compound increased with reaction temperature.The pyrolysis products included heterocyclic hydrocarbons,ketones,carboxylic acids,aldehydes,phenols,olefins,alcohols and aromatic hydrocarbons and other compounds,which had baking,sweet aroma,burnt-sweet,cocoa-like incense,floral and milky aroma notes.The synthetic product possessed strong DPPH free radical scavenging and reducing capacity and could be regarded as a potential antioxidant.关键词
