摘　　要：建立了同时分析2,4-滴、氯吡脲、沈农丰产剂2号3种常用坐果激素主要成分2,4-滴、1-(2-氯-4-吡啶基)-3-苯基脲及对氯苯氧乙酸在番茄中的残留分析方法。结果表明:采用超高效美国Phenomenex Kinetex C18柱,以甲醇-水(用醋酸调至pH值3.0)体积比50∶50为流动相,流速1.0mL/min,可以较好地分离3种坐果激素的主要成分。应用该方法,在番茄果实匀浆中添加2,4-滴,添加质量分数在0.10～2.00mg/kg范围时,回收率为88.72%～91.01%,变异系数为2.63%～4.63%;1-(2-氯-4-吡啶基)-3-苯基脲添加质量分数在0.05～2.00mg/kg范围时,回收率为88.53%～92.41%,变异系数为3.15%～6.73%;对氯苯氧乙酸添加质量分数在0.10～2.00mg/kg范围时,回收率为94.17%～96.29%,变异系数为5.99%～6.78%。A residues analytic method was developed for the active constituents for 2,4-D,forchlorfenuron and Shennong tomato high-yielding agent,2,4-D,1-(2-chloro-4-pyridy) -3-phenylurea and 4-chlorophenoxyacetic acid.The results were as follows:with phenomenex kinetex C 18 column,mobile phase was methanol-water(pH 3.0)(50:50,by vol) ,and flow rate was 1.0 mL/min.The average of recoveries and coefficient of variations of the method were 88.72 to 91.01%and 2.63 to 4.63%for 2,4-D,88.53 to 94.21%and 3.15 to 6.73%for 1-(...
