中文摘要: 运用高效液相色谱四极杆飞行时间串联质谱（high-performance liquid chromatography coupled with quadrupole time-of-flight-mass spectrometry，HPLC-Q/TOF-MS）法对向日葵蜂花粉中的酚胺类化合物进行定性和定量分析。通过质谱数据解析和文献对照，向日葵蜂花粉中共鉴定出8 种酚胺类化合物，其中4 种为三-对-香豆酰亚精胺，4 种为四-对-香豆酰精胺。定量分析显示，鉴定的酚胺类成分在限定质量浓度范围内线性关系良好。建立的HPLC-Q/TOFMS 法能够对向日葵蜂花粉中的酚胺类成分进行准确、可靠分析。

Abstract:The qualitative and quantitative analysis of phenolamides in sunflower bee pollen was carried out by high-performance liquid chromatography coupled with quadrupole time-of-flight-mass spectrometry（HPLC-Q/TOF -MS）. By HPLC -Q/TOF -MS，a total of eight phenolamides including four kinds of tri -p -coumaroylspermidines and four kinds of tetra -p -coumaroylspermines were identified through mass spectrometric data analysis and comparison with literature. The regression equations showed a good linear relationship between peak areas and content of these compounds.The results showed that the HPLC-Q/TOF-MS method established could accurately and reliably analyse phenolamides in sunflower bee pollen.
