In this quantitative examination of melanin was detected in 41 isolates of fumigatus. It was found that the significance of the difference in which the production of melanin (p ˂ 0.001) was the range of melanin extracted from fumigatus between (1.2 - 3.1 mg/mL). The isolates AFU1, AFU14, AFU29, AFU30, and AFU41 indicated that the maximum production ranged between (2.9-3.1 mg/mL). 2 hours at 100°C. It has similarities with standard melanin characters, and the same chemical characters of melanin extracted from the hymen of Bjerkandara adusta have been achieved according to a study (14) meaning there is similarity with standard melanin. The overlay of IR spectra of synthetic melanin extracted from fungal cultures showed a high degree of similarity. Purification of melanin from A. fumigatus. Wave numbers shown in 3381, 2927, 1867, 1531, 1404, 1073 and 651 cm-1 The wave range can be traced to the following chemical groups: 3381 cm-1 attributed to OH bonds, 2927 cm-1 to HC or HC = 0 bonds 1404 (C-CH3), and 651 cm -1 to (acyclic) CH2 bonds.
