title: [Studied on the identification of Fructus amomi from its confusable varieties by Fourier transform infrared spectroscopy].
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.
