This paper uses Fourier transform infrared spectrometer with OMNI sampler to distinguish Fructus amomi from their confusable varieties, i. e. Amomum aurantiacum H. T. Tsai et S. W. Zhao, Amomum chinense Chun ex T. L. Wu, Alpinia chinensis (Ketz.) Rosc and Alpinia japonica (Thunb.) Miq. IRs of Amomum villosum Lour., Amomum longiligulare T. L. Wu and Amomum villosum Lour. Var xanthioides T. L. Wu et Senjen are resemble, and they are markedly different from the FTIR of the confusable varieties. Repeat experiments were processed with different samples of the same set, and the probability is 1.000. The result shows that FTIR can be directly used to distinguish Fructus amomi from their confusable varieties.
本文采用配有OMNI采样器的傅里叶变换红外光谱仪,对阳春砂及其易混淆品种,即红壳砂仁、华阳春砂、华山姜和山姜进行鉴别。阳春砂、长果砂仁及绿壳砂仁的红外光谱相似,与易混淆品种的傅里叶变换红外光谱有明显差异。对同一组不同样品进行重复实验,概率为1.000。结果表明,傅里叶变换红外光谱可直接用于鉴别阳春砂及其易混淆品种。
