在非法添加物风险监测过程中,于声称具有减肥功效的压片糖果中发现一种酚丁结构类似物。根据其高分辨质谱碎片离子裂解规律,采用超高效液相色谱-四极杆轨道阱质谱(UPLC-Q-Orbitrap MS)对该物质进行了结构表征,结合核磁共振氢谱(
1
H NMR)数据,确定该化合物为泻药成分酚丁的衍生物双己酚丁。该物质与双醋酚丁、双丙酚丁互为同系物。建立了酚丁结构类似物双醋酚丁、双丙酚丁和双己酚丁的超高效液相色谱-三重四极杆质谱(UPLC-QQQ MS)测定方法。3种物质在0.5~50 ng/mL范围内线性关系良好,检出限均为0.025 mg/kg,定量下限均为0.050 mg/kg,在压片糖果和固体饮料基质中3个加标水平下的平均回收率为82.6%~114%,相对标准偏差(RSD,
n
=6)为1.3%~6.6%。该方法前处理简单、灵敏度高、准确度好,适用于食品中非法添加双醋酚丁、双丙酚丁、双己酚丁的测定。
A new oxyphenisatin analogue was discovered from a pressed candy claiming to be a weight loss product during the inspecting and monitoring of illegal adulteration. According to the law of ion fragments in the high-resolution mass spectrum of oxyphenisatin analogues,the unknown compound was characterized by ultra high performance liquid chromatography equipped with quadrupole-orbitrap mass spectrometry(UPLC-Q-Orbitrap MS). Combined with the
1
H NMR spectrum,the unknown compound was finally identified as oxyphenisatin dihexylester,a derivative of oxyphenisatin known as a cathartic drug. Oxyphenisatin dihexylester was a homologous compound of oxyphenisatin diacetate and oxyphenisatin dipropinate. Ultra high performance liquid chromatography-triple quadrupole mass spectrometry(UPLC-QQQ MS) was applied to the quantification of oxyphenisatin diacetate,oxyphenisatin dipropionate and oxyphenisatin dihexylester. There were good linear relationships for the three analytes in the range of 0.5-50 ng/mL. The limit of detection and limit of quantification were 0.025 mg/kg and 0.050 mg/kg,respectively. Recover
ies at three spiked levels in pressed candies and solid drinks were ranged from 82.6%-114%,with relative standard deviations(RSDs,
n
=6) of 1.3%-6.6%. The method has the superiorities in simple pretreatment,high sensitivity and good accuracy,which can be applied to the detection of illegal additive oxyphenisatin diacetate,oxyphenisatin dipropinate and oxyphenisatin dihexylester in foods.
