Abstract:
Antioxidant and free radical scavenging ability of the six fungal pigments were assessed using different methods viz., lipid peroxidation, reducing power, superoxide radical anion, hydroxyl radical, nitric oxide, metal chelation ability. The pigment extract exhibited a concentration-dependent radical scavenging activity in all the assays. The scavenging activity of pigment extract in the reducing power assay was found to be significantly higher than that in other methods. The scavenging effect of Thermomyces pigment extract on all the assays were very high followed by Chaetomium in all the concentrations.
