Isolation of an Antioxidative Substance Produced by Aspergillus repens
Abstract:
The acidic fraction of an extract of the culture liquid of Aspergillus repens MA0197 showed strong antioxidative activity when tested by the ferric thiocyanate and TBA methods. Chromatographic purification of this acidic fraction gave an active substance identified as Neoechinulin A. This compound showed higher antioxidative activity than α-tocopherol and could be expected to act as an antioxidant in Katsuobushi.
