In this paper, two groups of Chinese herbs are investigated, one includes four species of rhubarb in which only one is used to treat against diseases and illnesses as Traditional Chinese Medicine, the other group is a common anemarrhena rhizome, it is found to mix with different materials in it. Both of them are directly identified by means of Fourier transform Raman spectroscopy for the first time. The tiny, delicate varied chemical components of different raw Chinese herbs lead to different characters in vibration frequency of Raman functional groups. It is found that the vibration frequency variance follows a certain specific regularity. The method is more precise and quick than traditional approaches. What is more, it will not damage samples.
本文对两组中药材进行了研究，一组包括四种大黄，其中只有一种作为传统中药用于治疗疾病，另一组是常见的知母根茎，发现其中含有不同的成分。首次通过傅里叶变换拉曼光谱法对它们进行直接鉴别。不同生中药材微小、精细的化学成分差异导致拉曼官能团振动频率具有不同特征。发现振动频率差异遵循一定的特定规律。该方法比传统方法更精确、快速。而且，它不会损坏样品。
