摘要
目的:建立滇黄精药材的红外指纹图谱,为其质量控制提供参考。方法:收集不同产地滇黄精药材12批,采用傅里叶变换红外光谱仪建立其红外指纹图谱,并进行相似系数评价。结果:滇黄精共有7个红外指纹特征峰,分别为3 353.6 cm-1、2 933.2 cm-1、1 623.8 cm-1、1 419.4 cm-1、1 128.2 cm-1、1 051.0 cm-1、825.4 cm-1,12批药材相似系数均大于0.900。结论:此法具有良好的精密度、重复性、稳定性,可用于滇黄精药材的质量评价。
Objective: To establish Fourier transform infrared spectroscopy(FTIR)spectrum of Polygonatum kingianum. Methods:The fingerprints of P. kingianum were established by Fourier transform infrared spectrometer, and the similarity coefficient was evaluated. Results: There were seven characteristic peaks(3 353.6 cm-1, 2 933.2 cm-1, 1 623.8 cm-1, 1 419.4 cm-1, 1 128.2 cm-1,1 051.0-1, and 825.4 cm-1) in the typical fingerprint of P. kingianum, and the similarity coefficient was greater than 0.900.Conclusion: The method of FTIR fingerprint can be used for the quality evaluation of P. kingianum.
