Abstract: The structure characteristics of sesame melanin was studied by elemental analysis, UV spectra, IR spectra, 1HNMR, 13CNMR and alkali fusion/GC-MS. The study shows that aromatic rings with the substitutes of aliphatic, phenolic, carboxy and amino form the bio-macromolecule with conjugation system.
