摘 要:
本文利用超声-微波协同萃取法提取甘草多糖,并用分光光度法检测甘草多糖对DPPH自由基、羟自由基(·OH)和超氧阴离子自由基(O2^-·)的清除能力。结果表明,甘草多糖溶液对DPPH自由基、·OH和O2^-·均具有较好的清除作用。[著者文摘]

Abstract:
The study uses ultrasonic - microwave synergistic extraction technique to extract polysaccharides of Glycyrrhiza uralcnsis Fisch and tests the scavenging quality of polysaccharides on DPPH free radical, hydroxyl free radical ( · OH ) and super oxide free radical ( O2 ^- ·) by spectrophotometry. The result shows that polysaccharides has good scavenging effect on DPPH · , · OH and O2^-.[著者文摘]
Key words:
polysaccharides in Glycyrrhiza uralcnsis Fisch; DPPH free radical; hydroxyl free radical; super oxide free radical
