Allelopathic activity of volatile substance from submerged macrophytes on Microcystin aeruginosa
چکیده انگلیسی

Considerable attention has been paid on the allelopathic potential of aquatic macrophytes against blue-green algae. This study compared inhibitory activity of volatile compounds that were contained in two submerged macrophytes, Ceratophyllum demersum and Vallisneria spiralis, on Microcystin aeruginosa. When the concentration of essential oils was 100 mg/L, the antialgal activities for fresh macrophytes were similar between C. demersum and V. spiralis but stronger than those for dry macrophytes. Essential oils from C. demersum in dry macrophytes showed stronger antialgal activity than those from V. spiralis. There exists a positive correlation between the concentration of the essential oils and the inhibitory activity. The essential oils were composed of fatty compounds, terpenoids, phenolic compounds, phthalates, and some unknown compounds. More than 40% of the essential oils from fresh macrophytes were composed of phthalates, whereas approximately 70% of those from dry macrophytes were composed of lipid compounds and terpenoids. However, approximately 20% of the essential oils from fresh macrophytes were composed of unknown compounds, which were unstable and undetectable in dry macrophytes. Therefore, their chemical structures and bioactivities need further study.
