摘 要:采用高效液相色譜法,使用正相手性柱,以v(正己烷)∶v(異丙醇)=50∶50為流動(dòng)相,在流速為1.0 mL/min,檢測波長(cháng)為210 nm的條件下,對20%精甲·氰霜唑懸浮劑中的精甲霜靈進(jìn)行定量測定。使用反相ODS柱,以v(乙腈)∶v(水)=65∶35為流動(dòng)相,在流速1.0 mL/min、檢測波長(cháng)280 nm的條件下,對20%精甲·氰霜唑懸浮劑中的氰霜唑進(jìn)行定量測定。結果表明,精甲霜靈和氰霜唑的線(xiàn)性相關(guān)系數分別為0.9990和0.9990,標準偏差分別為0.09和0.03,變異系數分別為0.008%和0.004%,平均回收率分別為99.96%和100.06%。

Abstract:The content of Metalaxyl-M in Metalaxyl-M+Cyazofamid 20% SC was determined by HPLC using a normal phase chiral column, a mixture of n-hexane and isopropanol (50/50(v/v)) as mobile phase, a flowing rate of 1.0 mL/min, and a detection wavelength of 210 nm. The content of Cyazofamid in Metalaxyl-M+Cyazofamid 20% SC was determined by HPLC using a reverse phase ODS column, a mixture of acetonitrile and water (65/35(v/v)) as mobile phase, a flowing rate of 1.0 mL/min, and a detection wavelength of 280 nm. The experimental results indicated that the correlation coefficients of linearity for both Metalaxyl-M and Cyazofamid were 0.9990; the standard deviations were 0.09 and 0.03, respectively; the coefficient of variations were 0.008% and 0.004%, respectively; and the mean percent recoverys were 99.96% and 100.06%, respectively.
Key words:Metalaxyl-M; Cyazofamid; HPLC
