In addition, NMR is one of the most powerful techniques to explain the structure of chemical compounds.In the present study, the biodiesel obtained from S. bijugatus was
analyzed by NMR spectroscopy. The analysis report confirmed
the presence of a strong singlet peak at d 3.7 ppm and a triplet of
a-CH2 protons at d 2.3 ppm. These two distinct peaks confirmed
the presence of methyl groups in biodiesel of S. bijugatus.
