dc.descriptionMelanin extracted from Auricularia auricula fruiting bodies (AAFB) was examined by element analyzer, amino acid analyzer, inductively coupled plasma-optical emission spectrometry. Elemental composition analysis revealed that main component of AAFB melanin was pheomelanin. Amino acid analysis showed that 16 amino acids were found in AAFB melanin and total amino acid content was 321. 63 mg/g. There were 13 detectable metal elements in AAFB melanin, which was rich in Ca, Fe, Cu and Zn. In addition, AAFB melanin exhibited stronger scavenging activities on 2,2-diphenyl-l-picrylhydrazyl (DPPH) radical, superoxide radical and hydroxyl radical with IC50 values of 0.18, 0.59 and 0.34 mg/mL, respectively. These results indicated that AAFB melanin might be potentially used as a natural antioxidant.
