  1. 1The ion with the highest relative intensity was used as the precursor ion for quantification.
  2. 2Two product ions were used for the MRM analysis. The upper ion was used for quantitative analysis and the lower ion was used for qualitative analysis, which could guarantee the precision of the analytes.
  3. 3The retention time was determined by three different individual analyses (n=3).
