Abstract

Detritus of the seagrasses Zostera noltii and Z marina collected on the beaches of Arcachon Lagoon France over a 3year period was screened as a new source of zosteric acid ZA This natural sulphated phenolic acid is a high valueadded product capable of preventing settlement of marine organisms and protecting crops from fungal diseases The seasonal variation of the ZA content was quantified in methanolic and aqueous crude extracts using highperformance liquid chromatography The concentration found ranged from 65 to 456 μg g−1 dry wt for Z noltii and 51–692 μg g−1 dry wt for Z marina respectively This is the first report of ZA in Zostera noltii Detrital leaves of Zostera have never before been screened for their bioactive substances These results show that this low cost very abundant and renewable but heretofore unused marine resource has potential as a source of a rare and naturally occurring bioactive product
