中文摘要：

目的：对祖师麻药材进行红外光谱的结构特征的分析和鉴别.方法：以傅里叶变换红外光谱、二阶导数光谱、共有峰率和变异峰率的双指标序列及聚类分析等方法对本品进行结构及指纹图谱分析.结果：确定10批全国购置及采摘的祖师麻药材红外光谱的8个共有特征吸收峰,3种基源植物相对对照药材的共有峰率波动范围为77％～ 85％,变异峰率波动范围为11.8％ ～29.4％,4种伪品相对对照药材的共有峰率仅在63.6％ ～71.4％,且变异峰率波动较大.结论：应用红外光谱可对祖师麻进行快速鉴别,且方法可靠、易行.

英文摘要：

Objective：To identify and analytical ten samples＇ infrared spectroscopy of wild Zushima.Method：Using the 1D spectra,second derivative spectra,common peak ratio and variant peak ratio and identify research to structure and fingerprint analysis.Result：The study obtains eight common characteristic absorption peaks of Zushima,and its common peak ratio and variant peak ratio fluctuate between 77％-85％,11.8％-29.4％ respectively,but for the four spurious breeds,its common peak ratio fluctuate between 63.6％-71.4％,and variant peak ratio fluctuates greatly.Conclusion：Zushima canbe identified quickly by infrared spectroscopy,and the methed in reliable and feasible.
