Undamaged Determination of Raw Plant Medicinal Drugs with Fourier Transform Raman Spectroscopy

Sun Sunqin; Zhou Qun; Zhang Xuan; Wang Zhao; Yu Jianyuan (Department of Chemistry, Tsinghua university, Beijing 100084) (kaifeng Medical Institute,Kaifeng 475001) (Department of Biology,tsinghua University,Beijing 100084)  
Twenty-three common used Chinese medicinal raw materials were directly determined with Fourier Transform Raman spectroscppy for the first time. Varied chemical components of different medicinal materials lead to different characters in vibration frequency of Raman functional groups. It was found that the vibration frequency variance follows a certain specific regularity. This method is relatively more precise and quicker, and without damage of the sample.
