Simultaneous determination of α-thujone, β-thujone and camphor in infusion of sage using Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy
Abstract
Determination of α-, β-thujone and camphor in sage infusions was achieved using attenuated total reflectance infrared Fourier transform infrared spectroscopy (ATR-FTIR) (spectral region 1801-1408 cm<sup>-1</sup> in 2<sup>nd</sup> derivative form) and partial least square method (PLS) . The correlation coefficients (<i>R</i><sup>2</sup>) and the root-mean- square error of calibration (RMSEC) of α-, β-thujone and camphor were 0.99, 0.0210, 0.96, 0.0180 and 0.99, 0.0697, respectively. The proposed method is simple, rapid and economical.
