ATR-FTIR技术在进口血竭掺伪鉴别中的应用

ATR-FTIR Technique in Identification of Adulteration in Imported Draconis

目的:利用傅里叶变换衰减全反射红外光谱技术(ATR-FTIR)对进口血竭中的掺伪物质进行快速鉴别。方法:根据进口血竭与松香、达玛树脂、国产血竭对照药材的红外光谱对比图来对进口血竭中的掺伪物质进行快速鉴别。结果:27批进口加工血竭中有13批掺入了松香,3批掺入了达玛树脂,4批为国产血竭冒充,严重影响了进口血竭的质量。结论:傅里叶变换衰减全反射红外光谱技术操作快速简便,适合中药的快速鉴别。

Objective： Fourier transform attenuated total reflection infrared spectroscopy（ATR-FTIR） was applied for a quick identification of adulteration in imported draconis. Methods： The FTIR figures of imported dracosin,darma resin and Chinese dracosin were contrasted to quickly identify the adulteration in all the materials. Results： Rosin was mixed in 13 batches in all the 27 batches of imported draconis,resin in 3 batches and Chinese draconis was substituted in 4 batches. These seriously affected the quality of the imported draconis. Conclusion： Fourier transform attenuated total reflection infrared spectroscopy is easy and convenient for operation and is suitable for quick identification of traditional Chinese medicine（TCM）.
