三叶木通药材的FTIR光谱研究

目的 研究三叶木通F17R图谱的鉴别方法.方法 利用傅里叶变换红外分析仪,分别测定不同产地的三叶木通生药材的红外吸收图谱.结果 KBr直接压片法测定所得的图谱,在1737～1032 cm-1间不同产地三叶木通的红外吸收峰的峰值、峰位、峰形和峰强等存在一定差异,可作为三叶木通的鉴别依据.结论 本方法 快速、准确,专属性强,重现性好,操作简便,可为三叶木通生药鉴定提供红外光谱的鉴别指标.

Study on FTIR Spectroscopy of Akebia Trifoliate

Objective To study the identification method of Akebia trifoliata(Thunb.) Koidz. by Fourier Transform Infrared (FTIR) Spectroscopy. Methods FTIR Spectroscopy was measured of Akebia trifoliate collected from different production areas. Results At the range of 737-1032cm-1, the Spectroscopy of Akebia trifolia of different production areas showed variances in peak value of infrared absorption, peak position, peak shape and peak strength, which can be regarded as identification evidence for Akebia trifoliate. Conclusion This mehthod is rapid, reliable, simple and effective. FTIR can be used as the identification index for Akebia trifoliate.
