中文摘要: 樱桃番茄果脯为我国的出口创汇产品,矮壮素残留逐渐成为制约其出口的瓶颈,研究建立一种矮壮素残留的检测方法。以樱桃番茄果脯为研究对象,通过甲醇提取矮壮素,对提取物采用强阳离子柱固相萃取(SPE)分离净化,采用高效液相色谱/质谱/质谱进行检测,并对检测方法的可靠性进行分析。结果表明,建立的检测方法检出限和定量下限分别为0.01 mg/kg和0.02 mg/kg,加标回收率在73.33%~90.60%之间,精密度在3.34%~7.87%之间。该检测方法为调查番茄加工品中矮壮素本底含量以及为后续降解矮壮素残留提供方法基础。
Abstract:Cherry tomato preserves are agricultural products for export in China,and the residues of chlormequat chloride have become a bottleneck restricting its export,therefore,a detection method of the residues was established.The processed products of cherry tomato preserves were selected as the research object,the chlormequat chloride was extracted through the methanol,then the extraction was separated and purificated by strong cation solid-phase extraction (SPE)and detected by HPLC/MS/MS,the reliability of detection method was analyzed at the same time.The results showed that the detection and quantification limit of the method was 0.01 mg/kg and 0.02 mg/kg respectively,the recovery was 73.33%-90.60%and the precision was 3.34%-7.87%.The method provided a basis for the investigation of the content of chlormequat chloride in tomato and the degradation of chlormequat chloride residues.
