Sample handlingAliquots (100 ?L) of the extracts delivered to MSU were transferred into 200 ?L glass inserts, and the inserts were placed into microcentrifuge tubes. Solvent was evaporated under vacuum at room temperature in a SpeedVac, and residues were reconstituted
Sample storage temperature-20?C
Protocol when analyzing samplesBefore analysis of each batch of samples, the mass scale of the mass spectrometer was calibrated using infusion of 0.1% aqueous phosphoric acid. After column equilibration, one methanol/water (50/50 v/v) injection was performed. Standard solutions (0.25,
