Abstract:Following the isolation and purification of active compounds secreted by algicidal bacteria L7, the analytical methods of L7, LC-MS, UV, IR and TLC were applied to identify the active compounds .The LC-MS showed that the 12# component contains five compounds, whose molecular weights are 243.7, 364.0, 508.1, 602.1, 678.7, respectively. The results of UV indicated that the structure of algicidal compounds might contain two conjugated and unsaturated bonds. The results of IR and TLC indicated that the active compounds might contain aromatic aldehyde, amino acid, alcohol or the saccharide, but not phenol.
