The obtained graph from FTIR analysis Fig were compared to the standard peaks from , and a comparative tabulated result was obtained in Table . 1395.42 cm -1 Symmetric bending of tertiary carbon in the isopropyl group 1100-900 cm -1 1121.52 cm -1 CH3 rocking On comparing the peaks and their significant, it is observed that the obtained peaks are in very close relations with the standard peaks, thus we can confirm the extracted compound to be thymoquinone.
