The high-resolution primary mass spectrum of each parent ion was provided at the top left corner in each panel. The accurate mass and mass error (ppm) of four compounds in the standard and each measured sample were listed in the Supplementary information Table 6. See Supplementary information Table 7 and Supplementary Information Table 13 for more detailed parameters and conditions used in the MRM methods.
