摘要
The present paper used many kinds of mensuration of FTIR spectroscopy to determine traditional Chinese drugs-Rhizoma Atractylodis Macrocephalae. Comparing the horizontal attenuated total reflection-Fourier transform infrared spectra(HATR-FTIR) of xylem and outer layer parts of cuticle indicates that there are more butenolide and its derivatives in outer layer parts of cuticle. Much more chemical materials could be found in fresh sample than in drying sample, possibly due to the decreased amount of naphtha in the drying sample. The HATR-FTIR of xylem of Rhizoma Atractylodis Macrocephalae and its confusable varieties were transformed into second derivative FTIR to make sure whether the peak location is consistent. As a result, the difference is significant.
