Abstract
The acidic fraction of an extract of the culture liquid of Aspergillus repe ns MA0197 showed strong antioxidative activity when tested by the ferric th iocyanate and TBA methods. Chromatographic purification of this acidic frac tion gave an active substance identified as Neoechinulin A. This compound s howed higher antioxidative activity than alpha-tocopherol and could be expe cted to act as an antioxidant in Katsuobushi.
