For routine analytical purpose a method based on a combination of automated solid-phase extraction (SPE) clean-up and detection by Ultra-Performance Liquid Chromatography/Tandem Mass Spectrometry (UPLC-MS/MS) was developed for the determination of pyrrolizidine alkaloids (PA) in various food commodities. In this survey, honey, tea and herbal infusion samples from local retailers collected in 2012-2015 were obtained and analysed for their PA content. PA concentrations were found in 30% of the honey samples and in 42% of the tea and herbal infusion samples with levels up to 595 µg/kg. The survey included 17 individual PA, and their sum is also reported for each sample.
为了常规分析目的，开发了一种基于自动化固相萃取 (SPE) 净化和超高效液相色谱/串联质谱 (UPLC-MS/MS) 检测相结合的方法，用于测定各种食品中的吡咯里西啶生物碱 (PA)。在这项调查中，收集了 2012-2015 年当地零售商的蜂蜜、茶和草药浸剂样本，并分析了它们的 PA 含量。在 30%的蜂蜜样本和 42%的茶和草药浸剂样本中发现了 PA 浓度，含量高达 595µg/kg。该调查包括 17 种单独的 PA，并报告了每个样本中它们的总和。
