A HYDROXYBUTENOLIDE FROM SPHAGNUM SPECIES

Article abstract of DOI:10.1016/S0031-9422(00)97833-6

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.
