摘　　要：采用傅里叶变换红外光谱法分析鸡骨草与毛鸡骨草的红外光谱特征及其化学成分的差异。采集鸡骨草和毛鸡骨草两种药材整株和不同部位的FTIR图,运用二阶导数谱和半定量分析研究不同谱图间的差异。结果显示鸡骨草与毛鸡骨草均含挥发油、三萜类、黄酮、皂苷、多糖类等化学成分。黄酮类、皂苷类、多糖类成分含量均以毛鸡骨草高。"指纹"区的特征光谱显示,鸡骨草根部的黄酮类成分含量少于茎部、而皂苷类和多糖类成分含量高于茎部;毛鸡骨草黄酮类和皂苷类成分含量以叶部最高,根部最低;多糖类成分叶部最高,根部和茎部较低但二者含量相近。FTIR技术可以快速鉴别出鸡骨草与毛鸡骨草主要化学成分的差异,避免了用单一成分来衡量药材质量的优劣。The difference of constituents of whole plant as well as different parts of abrus cantoniensis and abrus mollis were studied by FTIR with secondary derivative spectra and semiquantitative analysis. The volatile oil, triterpenes, flavonoids, saponin, polysaccharides were contained in A. cantoniensis and A. mollis, but the contents of flavonoids, saponin and polysaccharides of A. rnollis were higher than A. cantoniensis. The characteristic spectra of IR fingerprint region of different parts in A. cantoniensis and A. mollis were as follows, flavonoids of stem were higher than root, but saponin and polysaccharides of root were all higher than stem in A. cantoniensis; the content of flavonoids, saponin and poly saccharide of leaf were highest,the flavonoids,saponin were lowest in root,while the content of polysaccharide were similar between root and stem in A. rnollis. In hence, FTIR could be used to fast identify the difference of main chemical constituents between A. cantoniensis and A. mollis, and avoid evaluating the quality of medicinal material rely on single component.
