中文摘要	[目的]建立超高效液相色谱-串联质谱法(UPLC-MS/MS)测定水稻糙米和植株基质中盐酸吗啉胍残留量。[方法]水稻糙米和植株经三氯乙酸振荡提取,用Oasis HLB或C_(18)固相萃取小柱净化,采用UPLC-MS/MS正离子扫描测定残留的盐酸吗啉胍。 [结果]糙米和植株的3种添加质量分数(0.05、0.5、3.0 mg/kg)的平均回收率分别为93.6%~105.4%和92.5%~109.2%,相对标准偏差分别为2.6%~7.2%和6.1%~7.7%。在糙米和植株中的检出限为0.005 mg/kg。 [结论]该方法操作简单,灵敏度高,定量准确,可用于水稻糙米和植株中盐酸吗啉胍残留分析。
英文摘要	[Aims] A method for the confi rmation and quantifi cation of moroxydine hydrochloride residues in brown rice and plant was established based on ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). [Methods] Brown rice and plant were extracted with trichloroacetic acid, cleaned up by Oasis HLB or C_(18) SPE cartridge column. The detection was performed by tandem mass spectrometry with electrospray ionization in positive mode (ESI+). [Results] Average recoveries of brown rice at three spiked levels (0.05, 0.5 and 3.0 mg/kg) were found in the range of 93.6-105.4% with RSD of 2.6-7.2%. Average recoveries of plant at three spiked levels (0.05, 0.5 and 3.0 mg/kg) were found in the range of 92.5-109.2% with RSD of 6.1-7.7%. Limits of detection (LOD) of brown rice and plant were 0.005 mg/kg. [Conclusions] The method is sample and suitable for routine and confi rmation analysis of moroxydine hydrochloride.
