傅里叶红外光谱法鉴别巴戟天及其伪品的研究

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: To develop a new method to identificate Morinda officinalis How with its confusable varieties quickly and excectly. Methods: Comparing the FTIR smilarities and tapical spectrum band correlation coefficient of Molinda officinalis How and M.umbellata L., Schisandera propingua (Wall) Baill. var. sinensis Oliv.,M.shunguaensis C.Y.Chen et M.S.Huang,Damnacathus officinarum Huang. Results: Tapical peak comparative analysis and tapical spectrum band correlation coefficient comparative analysis can identifined Morinda officinalis How from its their confusable varieties quickly. Conclusion: The results show that FTIR can be directly used to distinguish Morinda officinalis How from its their confusable varieties.
