傅里叶变换拉曼光谱法无损鉴别植物生药材

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

首次利用傅里叶变换拉曼光谱法（FT-Raman）直接测定了23种常用植物生药材。各种药材因所含化学成分的不同而反映出拉曼谱振动峰的差异，并遵循一定的变化规律。该方法快速，准确，不破坏样品。

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.
