Phenolic compounds are one major class of identified
allelochemicals present in many submerged macrophytes
[11-14]. The contents of total phenolic compounds (TPCs)
in the exudates of H. verticillata and V spiralis, and their
strong inhibitory effects on the growth of M. aeruginosa,
have been studied in our previous work [15]. This study
tried to identify and quantify individual phenolic compounds
exuded from
H. verticillata and V. spiralis, and
evaluate the allelopathic effects of the identified compounds
on the growth of M.
aeruginosa.
