双指标序列分析法分析吴茱萸的红外指纹图谱

Study on the Infrared Fingerprint of Evodia rutaecarpa Based on the Methods of Sequential Analysis of Dual-Indexes

目的:建立不同产地吴茱萸药材红外指纹图谱的鉴别方法,为吴茱萸的鉴定与品质评价提供新方法。方法:分别用吴茱萸药材粉末、氯仿提取物和无水乙醇提取物与溴化钾混合、压片,在4000～400 cm-1范围进行扫描,测得其红外指纹图谱,研究各样品之间的区别。结果:采用氯仿作溶剂对不同产地吴茱萸进行提取后的红外光谱图区别明显。结论:该方法可用于不同产地吴茱萸样品之间的鉴别。

Objective：To establish a method to identify the different origins of herba Evodia rutaecarpa by IR and provide a new technique for their identification and quality evaluation.Methods： The herba materials were extracted by chloroform and absolute alcohol,the powder and the extracts of Evodia rutaecarpa were mixed and pelleted with KBr.The slides were detected within 4000~400 cm-1 by FIR spectrophotometry.The Difference of samples was studied.Results：The infrared spectrums of Evodia rutaecarpa extracted by chloroform were obviously different.Conclusion：The method can be used to identify and appraise the different origins of herba Evodia rutaecarpa.
