One of the main products formed by peroxidative degredation of sphagnum acid in vitro is identified as (-)2,5-dihydro-5-hydroxy-4-<4'hydroxyphenyl>-furan-2-one, abbreviated as hydroxybutenolide.It seems to be the first report of the isolation of this compound.Peroxidase isozymes isolated from Sphagnum magellanicum have specific preferences in degrading sphagnum acid.Hydroxybutenolide is a naturally occurring component in Sphagnum spp.Occurrin g mainly bound to the cell wall.In contrast to sphagnum acid, hydroxybutenolide is not excreted into the surrounding medium by living Sphagnum plantlets. Key Word Index- Sphagnum magellanicum; Sphagnaceae; bryophyta; sphagnum acid; Degradation; peroxidase; isoenzymes; hydroxybutenoide; cell wall.
