英文摘要
An allelopathic substance was isolated from the methanol extract of the brown alga, Cladosiphon okamuranus. Extraction and purification of the active substance was monitored by bioassys against the conchospores of Porphyra yezoensis and Hetesigma akashiwo. The compound was identified as 6Z,9Z,12Z,15Z-octadecatetraenoic acid and its activity was then tested against 36 species of microalgae. Many of eukaryotes tested were affected at 5 ppm, but prokaryotes were unaffected at 25 PPM. The tetraunsturated fatty acid exterminated toxic red tide planktons such as Chattonella antiqua at 1 ppm concentration.
