Abstract


Abstract. The present study aims to fingerprint 7 aromatic herbs (basil, thyme, oregano, rosemary, sage, clove, cinnamon)  and an original derived formula (EPC), in order to find specific biomarkers by Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy. The studied aromatic herbs are well known for their antioxidant, antimicrobial and anticarcinogenic effect. After comparison of each plant FT-MIR spectra results concluded that these herbs are rich in phenolic compounds like flavonols, flavanols, phenolic acids, volatile phenols. The fingerprint region was set at 1400-1760 cm-1. FTIR spectroscopy is recommended as a reliable tool to evaluate the quality and authenticity of plant formulas.
