摘要
文章用紫外、荧光及红外三种光谱法对四种蒙药材进行了鉴别研究。分别用甲醇、石油醚、氯仿对蒙药材珍珠杆及其代用品钩藤、接骨木和混伪品桂枝进行了超声提取,对提取物分别进行了紫外光谱和荧光光谱测试,并对上述四种药材粉末的红外光谱进行了比较。结果表明,四种药材的紫外光谱特征峰相异。用荧光光谱鉴别时,对药材的提取溶剂有选择性,以甲醇作提取溶剂时四种药材的荧光光谱能有明显的差异。四种药材粉末的红外光谱有明显区别。
Identification study of four species of Mongolian herbal medicine by UV/fluorescence/IR spectroscopy was carried out. Ultrasonic extracts of Mongolian herbal medicine Rubus Sachalinesis Leveille and its substitute materials Sarnbucus williamsii Hance and Uncaria rhynchophylla （Miq.） Jacks. , and its false medicine Cirmamomum cassia Presl by methyl alcohol, petroleum ether and chloroform were obtained respectively, UV/fluorescence spectral scans for the above herbal medicines were taken and the spectra obtained were compared. Besides, the IR spectra obtained from the herbal medicines were compared. It was shown that the absorption peaks of UV spectra of the four species of Mongolian herbal medicine differ from each other when the methyl alcohol, petroleum ether and chloroform were used as extracting solvent, while there is a selectivity for the solvent when fluorescence spectrum was used to differentiate those medicines. Only when the methyl alcohol was used as extracting solvent, there are clear differences among the IR spectra of the four species of medicine. Therefore, three kinds of spectra are available in identifying the four species of herbal medicine. Among them, IR spectroscopy is noted for its more information about the fingerprints of herbal medicines, and being direct and simple, which is one of the methods worth recommending for identifying Mongolian herbal medicine.
