Abstract:
A vegetable melanin comprising between 6 and 8 monomeric units of vegetable flavanoids wherein each monomeric unit has the chemical formula C34-59O14-23H32-44N6-8, wherein the molecular weight of the vegetable melanin is between 4Ã—103 daltons and 6Ã—103 daltons, the amount of OH groups in the vegetable melanin is from 4.02 to 4.05 percent by weight of the vegetable melanin, the amount of &boxH;O groups in the vegetable melanin is from 1.04 to 1.06 percent by weight of the vegetable melanin, the amount of carbon in the vegetable melanin is from 49.44 to 49.52 percent by weight of the vegetable melanin, the amount of hydrogen in the vegetable melanin is from 5.10 to 5.73 percent by weight of the vegetable melanin, the amount of nitrogen in the vegetable melanin is from 1.15 to 1.24 percent by weight of the vegetable melanin, the amount of oxygen in the vegetable melanin is from 41.20 to 42.10 percent by weight of the vegetable melanin, the concentration of unpaired electrons in the vegetable melanin is from 1018 to 1022 spin/g, and the infra-red spectra of the vegetable melanin exhibits absorption bands at 3433 cmâˆ’1, 1620 cmâˆ’1, 1400 cmâˆ’1, and between 1200 cmâˆ’1 and 1100 cmâˆ’1.
