11种果仁类中药的FTIR光谱鉴别特征研究

FTIR Spectral Characteristics Identification of 11 Nutlet Species of Traditional Chinese Medicine

目的:快速、准确地鉴别果仁类中药。方法:采用分辨率高、重复性好、测定速度快的傅里叶红外光谱(FTIR)法,不经分离提取对11种果仁类中药进行分析研究。结果:果仁类中药有一些共同的红外光谱特征,同时各种中药有各自明显的红外指纹区,这些光谱特征对于果仁类中药的区别和种属间的关系研究具有鉴别意义。结论:该法简便、快速、准确,具有良好的鉴别应用价值。

OBJECTIVE：To identify nutlet species of traditional Chinese medicine（TCM）rapidly and accurately.METHODS：FTIR method which was characterized with high resolution ratio,good reproducibility and quick determination speed was used to analyze 11 nutlet species of TCM without extraction and separation.RESULTS：The results showed that there were some common IR spectral characteristics in these nutlet species of TCM,each of them had their distinct IR fingerprint region.These spectral characteristics were of significance to the identification of nutlet species of TCM and the study of the relationship between genera.CONCLUSIONS：The method is simple,rapid,accurate and suitable for the identification of drugs.
