摘    要:用傅里叶变换红外光谱对传统中成药板蓝根颗粒进行了研究.对同一厂家不同批次和不同厂家的板蓝根颗粒主要成分板蓝根和大青叶的红外光谱图及二阶导数谱图进行了比较分析,并将谱图进行可视化表达.结果显示,傅里叶变换红外光谱法结合二阶导数谱和谱图的可视化,能够有效地提取配方颗粒的特征指纹谱图,直观地反映出不同生产厂家产品质量的差别及同一生产厂家不同批号产品之间谱图的可重现性,从而实现中成药的无损快速鉴别,为中成药质量检测及监控提供一种方便、有效和直观的方法.

关 键 词:板蓝根颗粒  傅里叶变换红外光谱  二阶导数谱  可视化表达

Abstract:Banlangen granule is the main medicament of Banlangen,and is widely used for the prevention and cure of flu and viral infection.In the present article,Fourier transform infrared(FTIR) spectroscopy was used in the identification and analysis of the traditional Chinese medicine,Banlangen granule.The FTIR spectra of Banlangen granule samples coming from different companies and different batches of the same company were obtained.The curves of original absorbance and the second derivatives of the absorbance were analyzed for identification,and compared with those of indigowoad root and indigowoad leaf,which are their raw medicine materials.In addition,the infrared fingerprint spectra were visualized in the form of color bar figure.Results showed that characteristic fingerprint spectra of Banlangen Granule could be picked up effectively,and the products quality of different pharmaceutical factories and the spectra of different batch numbers from the same factory could be revealed directly by FTIR spectroscopy combined with the second derivative spectrum and fingerprint spectrum visualization of analytical data.Thus they were differentiated conveniently,accurately,quickly and directly with this method,providing a simple and effective technique in supervising and examining the quality of the traditional Chinese medicine.
Keywords:Banlangen granule  FTIR  Second derivative spectrurn  Spectrum visualization
