合成了2-羟基-1-萘甲醛缩2,6-二氨基吡啶席夫碱配体L,与硝酸钍反应,生成配合物ThL,研究了配体L和配合物ThL的抗菌活性。结果表明,配体L和配合物ThL对枯草杆菌、大肠杆菌、乳酸菌有良好的抑制作用,配合物ThL的抑菌活性好于配体L,最佳抑菌活性浓度是5 mmol/L。

The Schiff base ligand L consisted of 2-hydroxynaphthaldehyde and 2,6-diaminopyridine. The ligand L reaction with Th（NO3）4·4H2O generate corresponding complex ThL. The bacteriostatic activity of ligand L and complex ThL were investigated. The results indicate that both ligand L and complex ThL have good inhibitory effect for Bacillus subtilis,Escherichia coli and Lactic acid bacteria. Complex ThL bacteriostatic activity is much better than ligand L,the best concentrati...
