某些稀土水杨酸配合物的合成及其生物活性

Study on the Synthesis and the Biological Activity of the Complexes of RareEarth(Ⅲ) with O-Hydroxidebenoic Acid

合成了Ln[C6H4(OH)COO]3·3H2O(Ln=Yb、La、Nd、Ce),通过元素分析、IR及热重分析对其结构进行了表征,生物活性试验表明:配合物能显著促进水稻芽的生长。与对照组清水对比:当浓度为1mg/L时,配合物能最有效地促进水稻芽的生长,其中水杨酸钕的促长率能达到45.1%。

Four new solid coordination compunds of rare earth(Ⅲ)with O-hydroxylbenoic acid were synthesized.The general formulas of these complexes had been defined.The result of the trial in biological activities evidenced that these compounds had outstanding furtherance founction for paddy bud,while their consistency was 1mg/L,their furtherance founction was best,and the rate of furtherance of the compound (neodymium O-hydroxidebenoylate could reach 45.1%.
