Abstract

Melanin LEM236 was extracted and purified from Lachnum YM-236. Scanning electron microscopy showed LEM236 had a blocky, amorphous crystal structure with an irregular surface. Elemental analysis, infrared spectroscopy and 1H-NMR measurements indicated that the melanin had the structure model of a novel eumelanin-like pigment. The total antioxidant capacity of 1g/L the melanin was equivalent to that of 53.28±0.18 mmol/L -tocopherol. IC50 values of LEM236 for scavenging activity of ABTS•+, •OH and NO2- were 0.680 g/L, 0.759 g/L and 0.839 g/L, respectively.
