综述了目前国内外生物油成分分析的状况,重点介绍了红外光谱、核磁共振、质谱、气相色谱、高效液相色谱技术以及波谱-色谱联用技术在生物油有机小分子化合物结构表征方面的应用,评价了这些技术在生物油结构表征方面的作用和价值,并分析了生物油的理化特性及化学结构对检测分析产生的影响。此外,对生物油中的低聚糖和热解木质素等低聚物的分析检测研究也进行了介绍。最后,总结了波谱和色谱技术在生物油检测分析方面存在的主要问题,并对生物油中有机物检测与分析的发展趋势进行了展望。

An overview of domestic and foreign recent status on bio-oil analysis and characterization was presented, which focused on the applications of some spectroscopy and chromatography tech niques in chemical structure characterization of the small organic molecules, such as, Fourier trans form infrared spectroscopy（ FTIR）, nuclear magnetic resonance （NMR）, mass spectrometry （MS）, gas chromatography（ GC）, high performance liquid chromatography （HPLC） techniques, as well as the one- and two-dimensional chromatography coupling technology. The evaluations on the role and value of these techniques in structure characterization were afforded, and the detailed descriptions of the quality standards and some typical analysis methods of bio-oil were involved, and then the effects of physical and chemical properties of bio-oil on its separation and analysis were discussed. Moreo ver, the structure characterizations of oligosaccharide and pyrolytic lignin remained in bio-oil were in troduced. Finally, the main problems existed in bio-oil separation and analysis were summarized, and the prospect on the development trend for bio-oil separation and analysis was presented.
