The analysis and identification of chrysanthemums from the different producing areas by IR spectroscopy / 中成药

ABSTRACT

AIM: To get the IR spectrums of chrysanthemums from the different producing areas,and to find out the characters of IR spectrums,and the data of IR spectroscopy of chrysanthemums from the different producing areas. METHODS: Using Fourier transform infrared spectroscopy. RESULTS: The FTIR spectrums、Second-order derivative spectrums、Two-dimensional spectrums of chrysanthemums from the different producing areas have their obvious IR characters. CONCLUSION: We can discriminate chrysanthemums from the different producing areas macroscopically and holistically by IR spectroscopy.IR spectroscopy can give us the digital descriptions of TCM,so it is a new analytical method to discriminate TCM.
