合成具有抑菌活性的稀土配合物,筛选具有抑菌活性的中药成分做有机配体合成稀土配合物。在乙醇溶液中合成了八种小檗碱与稀土硝酸盐的二元配合物,采用元素分析、红外光谱、差热-热重和X射线衍射等方法进行表征,确定配合物的化学组成为RE(NO3)3(B)3(RE=La3+,Sm3+,Nd3+,Dy3+,Pr3+,Y3+,Ce3+,Gd3+;B=C20H18NO4)。研究了稀土配合物的抑菌活性,结果表明稀土配合物的抑菌效果较单独的稀土硝酸盐和小檗碱好。
Synthesis of rare earth complexes with antibacterial activity, screening antibacterial activity of traditional Chinese medicine composition of organic ligand synthesis of rare earth complexes. The binary complexes of eight kinds of berberine and rare earth nitrate were synthesized in ethanol solution and characterized by elemental analysis, FTIR, TG-DTA and X-ray diffraction. The chemical composition of the complex was determined as RE (NO3) 3 (B) 3 (RE = La3 +, Sm3 +, Nd3 +, Dy3 +, Pr3 +, Y3 +, Ce3 +, Gd3 +; B = C20H18NO4). The antibacterial activities of rare earth complexes were studied. The results showed that the antibacterial activity of rare earth complexes was better than that of rare earth nitrate and berberine alone.
