摘要: 对比了白桦、杂木、木屑以及蒸馏木屑4种木醋液的还原能力,二苯基苦基肼自由基(DPPH·)的清除能力和羟基自由基(·OH)的清除能力。结果表明,4种木醋液有较强的还原能力,其中还原能力最强的是木屑木醋液,半数有效浓度(EC50)为(1.73±0.06)g/L;4种木醋液可有效清除DPPH·,木屑木醋液清除效果最佳,半数抑制浓度(IC50)为(0.20±0.01)g/L;4种木醋液的·OH清除能力相对较弱,除木屑木醋液IC50为(9.69±0.20)g/L外,其他3种木醋液清除率均未达到50%。

Abstract: The reducing power and the scavenging activities against phenyl picryl hydrazine radical(DPPH·) and hydroxyl radical(·OH) of birch wood vinegar(BWV), miscellaneous wood vinegar(MWV), sawdust wood vinegar(SWV), and distillated sawdust wood vinegar(DWV) were determined. The results showed that four kinds of wood vinegar had strong reducing power and the reducing power of sawdust wood vinegar was the strongest with the half effective concentration(EC50) of(1.73±0.06) g/L. Wood vinegar could effectively scavenge DPPH·, and DPPH·scavenging activity of sawdust wood vinegar was the highest with the median inhibitory concentration(IC50) of(0.20±0.01) g/L. Wood vinegar showed relatively weak ·OH scavenging ability, except the IC50 of sawdust wood vinegar was(9.69±0.20) g/L, the ·OH scavenging rates of the other three kinds of wood vinegar couldn't reach 50%.

Key words: wood vinegar, antioxidant, reducing power, radical scavenging
