菊花不同炮制品的红外原谱、二阶导数谱及二维相关谱谱图分析

The Analysis on Processed Chrysanthemum by FTIR Spectrums Second-order Derivative Spectrums and Two-dimensional Spectrums

目的:分析药用菊花不同炮制品的红外谱图,找出怀菊花、炒菊花及菊花炭的红外原谱、二阶导数谱及二维相关谱的谱图特征,以期指导饮片炮制生产。方法:利用现代红外光谱技术,结合中药材红外光谱三级鉴定理论,在对谱图进行小波消噪的基础上,分析菊花不同炮制品的红外原谱、二阶导数谱及二维相关谱,提取红外谱图特征。结果:怀菊花、炒菊花及菊花炭红外原谱、二阶导数谱及二维相关谱特征性明显。结论:此技术用于中药材及中药炮制品的鉴别是可行的,且红外光谱法样品制备简单,仪器设备普及性强,在中药饮片的快速鉴别中具有一定的优势。
