Abstract

The aim of this paper is the estimation of Sideritis samples geographical origin using Diffuse Reflectance Fourier Transform Infrared Spectroscopy (DRIFTS) and chemometrics. The infrared spectra of 46 samples from eight greek regions were recorded in triplicate. The spectral region 1800-1530 cm<sup>-1</sup> of each average spectrum was correlated with the corresponding geographical region using TQ Analyst software. The samples were placed in the correct class at 91.3 %. The results show that the infrared spectroscopy can estimate the geographical origin of Sideritis samples.
