3种木质纤维原料热水抽出物抗氧化性的研究
Study on Antioxidant Activity of Hot Water Extractives from Different Lignocellulose Materials
摘要
Abstract
In this study,three kinds of lignocellulose materials(bamboo,eucalyptus and poplar)were prepared by hot water extraction(95℃,1 h,pulp consistency of 5%),and the antioxidant activities of their hot water extractives were compared.The difference of chemical structures among three kinds of hot water extractives was studied by means of Ultraviolet spectrophotometry,Gel Permeation Chromatography,Pyrolysis-Gas Chromatography Mass and Fourier Transform Infrared.The results showed that the antioxidant activity of the hot water extrac-tives of eucalyptus was the highest(semi-inhibitory concentration of 51.80 mg/L),which was superior to that of commercial antioxidant 2,6-di-tert-butyl-4-methylphenol(semi-inhibitory concentration of 87.99 mg/L).The antioxidant activities of the hot water extractives of dif-ferent lignocellulose materials were related to the content of phenolic hydroxyl groups and conjugated structures.The main components of the extractives were the intermediate products during the synthesis of organic macromolecules such as lignin and polysaccharide.关键词
