摘要: 建立高效液相色谱-串联质谱同时测定化妆中10种生物碱的分析方法。实验优化了提取条件、净化方式和仪器条件等参数。样品经80%(v/v)甲醇水溶液超声提取,离心后过滤。采用Waters BEH C18色谱柱分离,在多反应监测模式下测定,外标法定量。结果显示,在各自范围内,10种生物碱具有良好的线性关系,相关系数(R2)>0.9900,方法的检出限为5.0~12.5 μg/kg,定量限为12.5~50.0 μg/kg。在1倍、2倍和6倍定量限的加标水平下,10种生物碱的回收率为70.91%~116.75%,相对标准偏差为0.49%~9.98%(n=6)。该方法操作简单,适用于化妆品中10种有毒生物碱的快速筛查和定量分析。

Abstract: A high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was established for the determination of ten alkaloids in cosmetics. Extraction conditions, purification methods and instrumental parameters were optimized. The samples were ultrasonically extracted with 80% (v/v) methanol aqueous solution. The extracts were separated and filtered after centrifugation. The analytes were separated on a Waters BEH C18 column, and detected in the selected reaction monitoring mode. Ten alkaloids were quantified by the external standard method. The ten alkaloids showed good linearity with correlation coefficients (R2) greater than 0.9900. The limits of detection (LODs) and the limits of quantification (LOQs) of the ten alkaloids were in range of 5.0-12.5 μg/kg and 12.5-50.0 μg/kg, respectively. The average spiked recoveries in the cosmetics ranged from 70.91% to 116.75%, and the relative standard deviations (RSDs) ranged from 0.49% to 9.98%. The method can be used for the rapid screening and quantitative analysis of ten alkaloids in cosmetics.
