Syntheses and antibacterial activity of furan formaldehyde salicyloyl hydrazone rare earth complexes
摘要
Abstract
In order to study the antibacterial activity of hydrazone complexes, the ligand furan formaldehyde salicyloyl hydrazone ( HL) was synthesized from methyl salicylate, hydrazine hydrate and furfural in anhydrous alcohol. Then the four rare earth complexes RE ( HL) 2 ( N03) 3 ( RE = Pr, Eu, Tb, Y ) were synthesized by the reaction of HL and rare earth nitrate. The compositions and properties of the ligand and complexes were characterized by IR, UV, volumetric analysis, elemental analysis and molar conductance. The antibacterial activities of HL ligand and rare earth Pr ( Ⅲ) complexes on Phytophthora capsici Leonian, Fusarium oxysporum, and Alternaria altemata were also studied. The results show that HL and Pr( HL)2 ( NO3 )3 have no significant inhibition to Fusarium oxysporum (the inhibition rates < 70% ). The inhibition rates of HL ligand on Phytophthora capsici Leonian and Alternaria altemata are 71.0% and 82.5% respectively, and Pr(HL)2 (NO3)3 on Phytophthora capsici Leonian and alternaria altemata are 73. 0% and 85. 9% respectively. The complexes have better antibacterial activities than the corresponding ligand.关键词
