Physicochemical characteristics and antioxidant activity of the intracellular melanin from Lachnum sp.YM-236

摘要：

　　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 1 g/Lthe melanin was equivalent to that of 53.28±0.18 mmol/L α-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.
