Oxygenated Fatty Acids: A Class of Allelochemicals from Aquatic Plants
Polymers and High Performance Materials
Allelochemic effects of aquatic macrophytes on algae are discussed. Bioassays of chromatographic fractions from Eleocharis microcarpa Torr. indicate that oxygenated fatty acids are the causative agents. Methods of isolation of these materials from aquatic macrophytes and from natural waters are described. Purification and structure determinations show that prominent components of the fraction are C20 tri- hydroxycyclopentyl and C18 hydroxycyclopentenone fatty acids. Similar components were extracted from other aquatic plants. In addition, these components were extracted from pond waters. Implications to algal autoinhibition, algal succession in eutropic waters, and control of algal diversity are discussed.
