| 摘 要： | 为了直接准确地鉴别砂仁及其伪品的真伪,采用傅里叶变换红外光谱法直接测定砂仁及其伪品的红外光谱。结果阳春砂、绿壳砂、海南砂的红外光谱差别不大,而砂仁与其伪品红壳砂仁、海南假砂仁、华山姜及山姜的红外光谱吸收差别较大。对同一批次的不同样品进行了重复性试验,二阶导数傅里叶变换红外光谱正峰值的峰位一致率检验结果无显著性差异存在,说明可以采用FTIR法直接、快速、准确地对阳春砂、绿壳砂、海南砂与其伪品红壳砂仁、海南假砂仁、华山姜及山姜进行区别鉴定。

| Abstract: | 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. |
