The invention relates to the technical field of emergency detection, in particular to a method for detecting dephosphorylated nummulina velutipes and
toad tryptamine in a
urine sample. According to the method, a to-be-detected
urine sample is detected by adopting an Online SPE-LC-MS / MS method, a liquid
chromatographic column is a BEHC18
chromatographic column, and a
solid-phase extraction column is an online HLB small column. According to the method, online purification and enrichment of the sample can be automatically completed, the analysis time is short, the requirement for the dosage of the
urine sample is small, complex sample pretreatment is not needed, the
detection limit can reach 0.03 ng / mL, and the method has good sensitivity and accuracy and can meet the analysis requirement of the actual sample. The method is of great significance to identification of
food poisoning sources and
symptomatic treatment of patients.
