摘　　要：研究了马缨丹(Lantanacamara)叶提取物及其酚类化合物对水葫芦(Eichhorniacrassipes)生长及其生理生化指标的影响.结果表明,马缨丹鲜叶水提物对水葫芦生长有明显的抑制作用.在较高浓度(>30gFW.L-1)下6d可使水葫芦整株干枯死亡.经过高效液相色谱分离确定马缨丹水提物含有7种酚类化合物,分别为水杨酸、龙胆酸、雷琐酸、香豆素、阿魏酸、对羟基苯甲酸和6-甲基香豆素,在马缨丹鲜叶水提液中的浓度分别为50.95、13.46、5.28、3.36、2.92、2.19和0.34mg.L-1.7种化合物的混合物对水葫芦抑制程度最大,其次为水杨酸,再次为6-甲基香豆素、香豆素,对羟基苯甲酸对水葫芦也有明显的抑制作用,而龙胆酸、雷琐酸、阿魏酸对水葫芦的抑制作用较小.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 · 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, β-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 · 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 β-resorcylic acid and gentisic acid were not significant.
