| 摘 要：建立了一種同時(shí)分離復配制劑中吡唑醚菌酯和丙環(huán)唑的高效液相色譜法，使用Poroshell 120 EC-C18反相不銹鋼柱和具有可變波長(cháng)的紫外檢測器，以乙腈、甲醇和水為流動(dòng)相，采用外標法對復配制劑中有效成分進(jìn)行定性和定量分析。有效成分吡唑醚菌酯和丙環(huán)唑方法重復性相對標準偏差分別為0.49%和0.82%，均小于修訂后的霍維茨值RSDr，吡唑醚菌酯和丙環(huán)唑的線(xiàn)性相關(guān)系數為0.999 9和0.999 8，平均回收率分別為100.4%和100.6%。 |

| Abstract：A HPLC method was established for the simultaneous separation of Pyraclostrobin·Propiconazole in a compound formulations. Using Poroshell 120 EC-C18 reversed-phase stainless steel column and UV detector with variable wavelength, the active components in compound formulations were analyzed and quantified by external standard method using acetonitrile, methanol and water as mobile phases. The result showed that the variation coefficients were 0.49% and 0.82% which belowed the value of RSDr, the linear correlation coefficients of Pyraclostrobin and Propiconazol were 0.999 9 and 0.999 8, and the average recoveries were 100.4% and 100.6%, respectively. |
