Abstract

The chemical composition and scavenging effects of a kind of glycoprotein from tea on active oxygen free radicals were studied. The tea polysaccharides(TPS) were composed of arabinose, ribose, xylose, glucose and galactose. TPS(8.5-170 mg/L) could scavenge the .OH produced in deoxyribose-Fe2+ reaction and the scavenging rate was between 5.5% to 74.7%.

摘要

研究了一种茶叶糖蛋白的化学成分及其对活性氧自由基的清除作用。茶多糖（TPS）由阿拉伯糖、核糖、木糖、葡萄糖和半乳糖组成。茶多糖（8.5 - 170毫克/升）能清除脱氧核糖 - 亚铁离子反应中产生的·OH，清除率在5.5%至74.7%之间。
