Abstract
The overall O-1(2) quenching rate constants k(Q) for three meroditerpe noids from Mediterranean marine algae of the genus Cystoseira were mea sured using 1,4-dimethylnaphthalene 1,4-endoperoxide as a thermal sour ce of O-1(2) ((1) Delta(g)). The most active of the compounds tested h ad a k(Q) value which is comparable with that of alpha-tocopheroI. The se metabolites also act as inhibitors of methyl linoleate peroxidation , while their O-2(.-) quenching activity is rather low, similar to alp ha-tocopherol.
