目的:为了快速准确地鉴别巴戟天及其伪品。方法:采用傅里叶红外光谱法对巴戟天药材及其常见伪品羊角藤、铁箍散、假巴戟和恩施巴戟进行测定,通过比较一、二级红外谱图相似度和特定谱段相似系数对其真伪进行分析。结果:在一、二级红外谱图上均可根据特征峰比对分析法和特征谱段相似系数法快速鉴别巴戟天及其伪品。结论:红外光谱法用于巴戟天药材真伪鉴别准确、快速,可以作为巴戟天药材真伪鉴别的一种现代化检测方式。
Objective: In order to quickly and accurately identify Morinda officinalis and its counterfeit goods. Methods: The medicinal materials of Morinda officinalis and its common false calamus, ferruginous, pseudobacum officinale and Enshi officinalis were determined by Fourier transform infrared (FTIR) spectroscopy. By comparing the similarities and specific spectra of primary and secondary infrared spectra Segment similarity coefficient to analyze its authenticity. Results: Morinda officinalis and its counterfeit could be rapidly identified on the first and second-order infrared spectra based on the characteristic peak correspondence analysis method and the characteristic spectral similarity coefficient method. Conclusion: The method of infrared spectroscopy for the authenticity identification of medicinal plants of Morinda officinalis is accurate and rapid, which can be used as a modern detection method for the authenticity identification of medicinal plants of Morinda officinalis.
