摘要：

研究开发了7种新型稀土配合物。使用差热热重和红外表征了配合物，采用最低抑菌浓度实验，研究了配合物对4种（番茄溃疡病菌、向日葵菌核病菌、尖孢镰刀菌和胡萝卜黑斑病菌）农作物病原菌的敏感性；采用急性经口毒性和急性经皮毒性试验，考察其急性毒性。7种配合物均为低毒性药物，并且抑菌效果好。对向日葵菌核病菌最低抑菌浓度均为0.125 mg/mL。对番茄溃疡病菌抑菌效果最好的是Ce(NO3)3(B)3、Gd(NO3)3(B)3，最低抑菌浓度是0.125 mg/mL。对尖孢镰刀菌抑菌性最好的是La(NO3)3(B)3、Gd(NO3)3(B)3和Y(NO3)3(B)3，最低抑菌浓度是0.5 mg/mL。对胡萝卜黑斑病菌抑菌性最好的是Gd(NO3)3(B)3，最低抑菌浓度是0.5 mg/mL。结果表明7种新型稀土小檗碱配合物是一类广谱、高效、低毒的杀菌剂。

Abstract:

Seven new rare earths berberine complexes were synthesized and developed. The complexes are characterized the infrared spectra. Antibacterial of 4 kinds of difficult controllable crops bacterias (Clavibacter Michiganensis Subsp., Sunflower Hyphal Cluster Germ, Fusarium Oxysporum and Carrot Peutz bacteria) of the complexes were studied by inhibition zone and minimum inhibitory concentration test. Acute oral and acute dermal toxicity test were adopted in this experiment. The results indicated that 7 complexes were low toxicity pesticides and had good antimicrobial activity. To Sunflower Hyphal Cluster Germ, Minimum inhibitory concentration was 0.125 mg/mL. The best antimicrobial activity to Clavibacter Michiganensis Subsp. was Ce(NO3)3(B)3 and Gd(NO3)3(B)3. Their minimum inhibitory content was 0.125 mg/mL. La(NO3)3(B)3, Gd(NO3)3(B)3 and Y(NO3)3(B)3 to Fusarium Oxysporum had a better antimicrobial activity, which minimum inhibitory concentration was 0.5 mg/mL. The best antimicrobial activity to carrot Alternaria was Gd(NO3)3(B)3, its minimum inhibitory concentration was 0.5 mg/mL. Seven new rare earths berberine complexes were widespread and efficient pesticides with low toxicity.
