针对目前临床药物拉曼光谱的缺乏和药物检测领域的现状, 利用拉曼光谱技术对抗生素、 抗组织胺、 血凝酶和止吐剂等几类常用临床药物进行了拉曼光谱的测量和研究。 通过观测上述具有良好拉曼活性的药物样品拉曼光谱, 不仅确定了样品拉曼峰的位移、 强度和线宽, 还探索了其包络的线形等光谱特性。 通过分析和比较拉曼光谱图, 找出各药物间的异同; 对于那些由于拉曼活性低或拉曼光谱的复杂样品, 虽然暂时无法识别, 但也进行了尝试性的测量或提出了测量建议。 研究表明: 小分子药物的光谱特征很明显, 拉曼峰分布较广, 对其进行光谱识别简单易行; 而大分子都表现出较弱的光谱特征峰, 常常伴随复杂的包络, 不仅导致了对其光谱识别的困难, 也很难准确确定特征峰位置。 对于不同药物, 提出了用拉曼光谱测量和分析其药物成分的可行性, 并通过分析其拉曼光谱的特性, 为医学工作者识别和分析药物成分提供了实验证据。 不仅为建立药物的拉曼光谱数据库奠定了基础。 还使业界看到了快速识别和检测药物的前景, 从而促进拉曼光谱技术在药物检测上的运用。

Aiming at the shortage of the Raman spectra of drugs and the current situation of drug testing, we have applied Raman spectroscopic technique to several kinds of medicine, such as antibiotics, antihistamine, hemocoagulase and antiemetics. The spectral properties for the samples with high Raman activity are investigated by observing their Raman spectra to yield the shift, intensity, and line width of the Raman peaks, as well as the line shape of Raman envelope. For those samples with weak Raman activity or complex structures that are hard to be identified, we have also made some tentative measurements or raise some suggestions for future measurement. Comparing the similarities or differences among many Raman spectra of drugs, it is evident that drugs with small molecule have apparent spectral characteristics, by which to recognize them is very feasible, while those with large molecule usually have weak peaks or complex envelope in their spectra, leading to a difficult recognition and uncertain peak positions. This work not only proposes to identify chemical ingredients of drugs by observing and analyzing their Raman spectra, but also provides experimental evidences for medical workers doing so. The present results lay the foundation for establish the database of Raman spectra for drugs, and point out the prospect for rapid identification and detection of drugs, promoting the application of Raman spectroscopy technology on drug detection to a certain extent.
