| Abstract: | In the present article the FTIR spectra of the xylems of Smilax glabra Roxb. and its three kinds of counterfeits were obtained by Fourier transform infrared spectroscopy(FTIR) with OMNI-sampler directly,fast and accurately.By adopting wavelet transform analytical method the samples were studied in detail.The results showed that wavelet transform could remove the noises and condense variable, and have the advantages of fast operating speed,high degree of accuracy,and no noise disposal.It will have a good application prospect in infrared spectroscopic analysis. |
