IR and its first derivative analysis for blank CO₂ solution (a), CO₂ solution treated with paraffin/methanol as negative control (b), CO₂ solution treated with A. judaica oil/methanol as tested solution (c), and CO₂ solution treated with thymol/methanol as positive control (d). A. judaica reduces the altitude of first derivative signal of CO₂ stretching showing almost the absorbance of equal amount of thymol.
