[Objective] In order to investigate the antialgal activities and species of the allelochemicals in Magnolia grandiflora leaves. [Method] The antialgal substances against microcystic aeruginosa from the extracts of magnolia grandiflora leaves were separated, purified and identified based on the activity test, using silica gel column chromatography, gel column chromatography and GC-MS method and combining the algae inhibition experiment. [Result] The maximum inhibition rate of the extracts of magnolia grandiflora leaves on microcystic aeruginosa growth was 97.4% with the concentration of 8 g/L. A large amount of antialgal substances were found in the n-butanol extracts of magnolia grandiflora and had very good inhibition effects on microcystic aeruginosa, which were mainly small molecule substances such as alcohols, ketones and esters. [Conclusion] A new idea on developing new algal inhibitors had been provided.
