Abstract: In this study,different parts of Meconopsis quintuplinervia were discriminated and identified by Fourier transform infrared spectroscopy (FT-IR) coupled with second derivative infrared spectroscopy.The findings indicated that different parts of M.quintuplinervia samples had dissimilar fingerprint characters in FT-IR spectra.Such spectral technique can provide structural information of the complicated samples.There were differences in the ratio of relative intensity of the characteristic peaks of FT-IR.The difference was amplified by the second derivative spectrum for the peak shape in 1517-1471 cm-1 and 1162-1107 cm-1. In conclusion,FT-IR spectroscopy combined with second derivative spectroscopy provided a powerful and useful approach for the identification of traditional medicines.
