- Abstract
To identify the characters and differences of the metabolites in different organs of water dropwort (Oenanthe javanica) and clarify the mechanism of allelopathy and algae inhibition of it, types and content of metabolites from different organs and culture water of floating bed water dropwort in different growth stages were analyzed using LC-ESI-MS metabolomics technology. In the culture water at the reproductive, seedling, and mature stages, 36 different phenolic acids and 24 different fatty acids were identified. The relative contents of the two types of allelochemicals at the seedling stage were significantly higher than those at the reproductive and mature stages. Eighteen phenolic acids could be detected in all different organs via targeted metabolomics technology. Ferulic acid and caffeic acid contents in leaves were (15.20 ± 1.98) ng·mg-1 and (37.26 ± 2.21) ng·mg-1, respectively. Thirty-three different types of fatty acid allelochemicals could be detected in all organs. The contents of stearic acid and myristic acid in the roots and leaves were (450.70 ± 14.32) ng·mg-1 and (39.54 ± 0.50) ng·mg-1, respectively, much higher than that in stems. Taken together, a variety of phenolic acids and fatty acids were accumulated in both water dropwort plants and the culture water. The release of these compounds could inhibit the growth of algae in eutrophic water. The leaves of water dropwort at seedling stage could be ideal materials for biological algae inhibitors production due to the remarkable content of phenolic acids and fatty acids.
