摘　　要：为研究烯唑醇配合物对微生物抑菌的稳定性,试验模拟室内不同时间的紫外照射、100℃不同时间水浴以及不同pH等处理方式对烯唑醇Co(Ⅱ)配合物抑菌稳定性进行研究,采用菌丝生长速率法测定松球壳孢菌的生长情况。结果表明:烯唑醇Co(Ⅱ)配合物经紫外照射以及100℃加热处理后,对松球壳孢菌的抑制活性不减,可见烯唑醇Co(Ⅱ)配合物在热、紫外照射条件下均具有极强的稳定性。而pH在6~7,抑菌能力有所下降,除此之外随着pH的改变,烯唑醇Co(Ⅱ)均呈现极强的抑菌活性,呈现较好的稳定性。该结果为烯唑醇Co(Ⅱ)配合物的生产、贮藏及在实践上的应用提供依据。In order to study the stability of diniconol complexes against microbial inhibition,a experiment was carried out to estimate the stability of Co(diniconazole)2 Cl2 by UV irradiation,heat treatment at 100℃and acid-base treatment under pH 2.0-pH 12.0.The growth of Sphaeropsis sapinea was determined by mycelial growth rate method.The results showed that the antibacterial activities of the Co(diniconazole)2Cl2 treated under above mentioned condition did not reduced,indicating that the Co(diniconazole)2Cl2 has excellent stability under all conditions except for pH 6 and pH 7.0.It provides useful experimental data for the production,storage and practical application of Co(diniconazole)2Cl2.
