[Objective]To explore the identification methods of FRUCTUS AMOMI in different production areas,to detect the infrared absorption spectra of FRUCTUS AMOMI in different production areas by FTIR,to switch the spectra by derivative spectra; and to find out the characteristic difference absorption of FRUCTUS AMOMI in different production areas. [Results]There were no significant differences in the infrared spectra of FRUCTUS AMOMI in different production areas. Some characteristic peaks showed up in the wavelengths of 600- 750 and1 300- 1 400 cm- 1after the fourth-order derivave spectra. Peak differences appeared in eight samples in the wavelengths of 1 000- 1 300,1 400- 1 500,2 800- 3 000 and 3 500- 3 800 cm- 1. [Conclusions] There were significant differences in the FTIR spectra of FRUCTUS AMOMI in different production areas after processed by derivative spectra. This method could better identify the FRUCTUS AMOMI in different production areas.
