Abstract Auxin metabolome affects almost every facet of plant development from hormone transport and biosynthesis to degradation. It also triggers several environmental responses. Measuring auxin biosynthesis can enable a better understanding of metabolism and hormonal activities during plant growth and developmental phases. Here we optimised a solid phase extraction (SPE) sample preparation and liquid chromatography-high resolution mass spectrometry \(LC-HRMS) method for profiling auxin metabolites in the tissues \(shoot and leaves) of the model plant system (Arabidopsis thaliana). We combined a sensitivity SPE sample preparation protocol with accurate LC-HRMS analysis to profile auxin metabolites in plant tissues.
