摘　　要：目的:石首鱼药材与其易混品棘头梅童鱼性状类似,不易区分,分析不同种类石首鱼药材及易混品的指纹图谱,为来自不同基原种类的石首鱼药材及易混品的鉴定提供依据。方法:采用红外光谱三级鉴定法对不同种类的石首鱼药材进行研究,提取红外谱图特征,观察比较不同基原石首鱼药材与棘头梅童鱼的区别。结果:所研究样品的一维谱图差异较小、相似度较高,二阶导数谱图每种样品都含有其特定峰,二维相关红外光谱中自动峰的峰数、峰位和峰强均有明显的区别。结论:红外光谱三级鉴定法可直观的鉴别石首鱼药材及其易混品,为准确、有效考察石首鱼药材提供了重要手段。Objective:The medicinal materials of Shishouyu(Larimichthys)are similar to its adulterant,Jitou Meitongyu(Collichthys Lucidus),which is difficult to distinguish.The fingerprints of different species of Shishouyu and their adulterants were analyzed to provide a basis for the identification of different species of Shishouyu and its adulterant.Methods:Three-level identification method of infrared spectrum was used to study different kinds of Shishouyu to observe and compare the differences between different primitive materials of Shishouyu and Jitou Meitongyu.Results:The one-dimensional infrared spectrums of the samples have little difference and high similarity,the second-order derivative spectrum of each sample has its specific peak.The peak number,peak position and peak strength of automatic peak in two-dimensional correlation spectrum are obviously different. Conclusions:Infrared spectrum three-level identification method can directly identify the medicinal materials of Shishouyu and their adulterants,which provides an important method for the accurate and effective investigation of Shishouyu.
