摘  要：
为建立蔬菜中矮壮素残留的高效液相色谱-电喷雾离子阱质谱(LC-ESI/MS)的检测方法,样品中的矮壮素残留采用甲醇-水-乙酸溶液提取,离心,分取部分上清液过SCX阳离子交换固体萃取小柱,LC-ESI/MS法测定,以保留时间和特征离子定性、外标法定量。结果表明,矮壮素在0.03～10mg/L范围内线性良好,线性相关系数为R2=0.9991,加标回收率为74.92%～103.28%,相对标准偏差为2.92%～10.48%,方法定量下限可达0.02mg/kg。

摘  要：
A analytical method using high performance liquid chromatography (HPLC) combined with electrospray ionization mass spectrometry (ESI/MS) was developed for determining chlormequat residues in vegetables.Samples were extracted with methanol/water/acetic acid,and the extract was then centrifugated.The supernatant was harvested and cleaned up on a SPE-SCX column before HPLC-ESI/MS analysis.Retention times and characteristic ions were used for qualification and external standard method for quantification.A good linear of the calibration curve developed was exhibited over a concentration range of 0.0310 μg/mL with a correlation coefficient of 0.9991.Average recoveries for chlormequat in 5 vegetables ranged from 74.92% to 103.28% with a relative standard deviation from 2.92% to 10.48%.The quantitative limit for chlormequat was 0.02 mg/kg.
