This paper studied-the effects of Lantana camera fresh leaves aqueous extract and its contained phenolic compounds on the growth and physiologic-biochemical indexes of Eichhornia crassipes. The results showed that this extract had obvious inhibitory effects on the growth and development of E. crassipes. When the concentration was higher than 30 g FW center dot L-1, it could kill E. crassipes after 6 days treatment. A total of seven phenolic compounds in the abstract were identified by HPLC, which were salicylic acid, gentisic acid, P-resorcylic acid, coumarin,. ferulic acid, p-hydroxybenzoic acid and 6-methyl coumarin, with the concentrations being, 50.95, 13.46, 5.28, 3.36, 2.92, 2.19 and 0.34 mg center dot L-1, respectively. The mixture of the seven compounds had the strongest inhibitory effect, followed by salicylic acid, 6-methyl coumarin, coumarin, and p-hydroxybenzoic acid, while the effects of beta-resorcylic acid and gentisic acid were not significant.
