武当山区重楼红外指纹图谱研究

目的:建立不同品种重楼属植物红外指纹图谱,为重楼药材的快速鉴别提供理论依据。方法:采用傅里叶变换红外光谱仪(FFIR)测定不同品种的重楼属植物,运用Nicolet Omnic Ver 8.2红外光谱处理软件对所获指纹图谱进行特征峰指认和二阶导数图谱对比分析。结果:不同品种重楼属植物的指纹图谱间有一定差异,二阶导数图谱比较差异较明显,可作为不同品种重楼属植物的鉴别特征。结论:红外指纹图谱法可快速鉴别不同品种重楼属植物,且操作简便、易行,对其他中药材的品种鉴定具有参考价值。

Study on Infrared Fingerprint of Paris Polyphylla in Wudang Mountain Area

Objective: To establish an infrared fingerprint spectrum of different varieties of Paris polyphylla and provide a theoretical basis for Paris polyphylla''s rapid identification. Methods: Using Fourier transform infrared spectroscopy (FFIR) to establish the IR fingerprint of different varieties of Paris polyphylla. Then the spectrogram was analyzed by Nicolet Omnic Ver8.0 Infrared Spectra. Results: The fingerprints of different varieties of the Paris polyphylla had certain differences. There were obvious differences by comparing their second derivative maps. So, it can be used as the distinguishing characteristics of the different varieties of the Paris polyphylla. Conclusion: Infrared fingerprint method can be used to quickly identify different varieties of Paris polyphylla. Moreover, it is simple and easy for manipulation. So, it has some reference meaning and guidance for the identification of other varieties of traditional Chinese medicine materials.
