| 摘 要： | 本文利用傅里叶变换拉曼（FT-Raman）光谱法无损快速鉴定了正品大黄与伪品大黄以及有掺伪物的知母样品。结果表明：大黄（西宁大黄）与伪品大黄（华北大黄，山大黄，水根大黄）在拉曼谱图中均有各自的特征峰，可容易地将它们区别开；知母样品中所掺杂的其他饮片，经与白芨的拉曼谱图比对，证实为白芨饮片，该方法具有快速，准确，操作简单，不需对样品进行提取分离，可直接进行测定的特点。 |

| Abstract: | 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. |
