[Simultaneous screening of pesticides and mycotoxins in dried goji berries and mulberries by QuEChERS-liquid chromatography-quadrupole-time of flight mass spectrometry]. [PDF]
Se Pu枸杞和桑葚中糖分含量较高且受生长环境影响，易受害虫和病菌侵袭，农药残留和真菌毒素是影响其质量安全的主要因素。基于此，本研究应用改进的QuEChERS方法结合液相色谱-四极杆-飞行时间质谱（LC-Q-TOF/MS）开发了一种简单、高通量、灵敏的分析方法，可实现对枸杞、桑葚两种浆果类药食两用物质中172种农药和11种真菌毒素的同时测定。样品经水化后用5%甲酸乙腈提取，4 g无水硫酸镁、1 g氯化钠进行盐析，经无水硫酸镁、N-丙基乙二胺（PSA）、十八烷基键合硅胶（C18）、多壁碳纳米管（MWCNTs）净化后，
