摘要
吡咯里西啶生物碱(pyrrolizidine alkaloids,PAs)是一类植物次级代谢产物,其中不饱和PAs及大部分PAs的氮氧化物具有多种毒性作用。PAs已被发现广泛存在于各类茶叶中,且成为导致我国茶叶出口受阻的主要污染物之一。本文综述了茶叶中PAs检测的前处理方法和色谱-质谱检测技术的发展,并展望其发展趋势;总结了不同国家茶叶PAs污染水平;分析了茶叶中PAs种类、不同茶叶的PAs差异以及茶叶与其他食品或农产品中PAs差异;解析了茶叶中PAs对人体的健康风险。我国茶叶PAs污染水平监测与风险评估研究相关数据处于缺失状态,急需开展茶叶中PAs污染来源与风险评估研究。
Pyrrolizidine alkaloids(PAs)are a class of plantsecondary metabolites,and unsaturated PAs and most pyrrolizidine alkaloid N-oxides(PANOs)have multiple toxic effects.PAs have been found widely in various kinds of tea samples,and have become one of the major contaminants hindering China’s tea export.This paper reviews the development of sample pretreatment methods for chromatographic-mass spectrometric detection of PAs in tea,and presents an outlook on future trends.Next,it summarizes the levels of PAs pollution in tea from different countries,and analyzes the types of PAs in tea,the occurrance of PAs in different teas,and the differences in PAs between tea and other foods or agricultural products.Finally,discusses the health risk of PAs in tea.Studies to monitor PAs pollution levels in tea and assess the health risk of PAs in tea are currently lacking in China.Therefore,it is urgent to clarify the source of PAs pollution in tea and assess the health risk of PAs in tea.
