and Collision Energy (CE) are stated in Table 1.
The BA derivatives exhibit intense protonated molecular ions [M+H]+ in MS spectra, and [M+Na]+ is also observed.
For the MS/MS spectra, the main fragment ions from d0-MASC labeled BAs are at m/z 208 and m/z 224, and d3-MASC labeled BAs give fragment ions at m/z 211 and m/z 227.
The representative MS/MS of (d0-MASC)2-TRY and (d3-MASC)2-TRY are shown in Fig. 2(A).
As can be seen from Fig. 2(A), the most abundant fragment at m/z 208 or m/z 211 is 10-methylacridone cation which can be expressed as [d0-MA]+ or [d3-MA]+.
And the MRM transitions of [M+H]+?[MA]+ were used for quantification analysis in our experiments.
In addition, the whole HPLC–MS/MS run were divided into three segments.
Segment I is set to waste, avoiding high concentration of 10-methyl-acridone-2-sulfonyl acid (MASC-OH) contaminate ion source.
Segment II and III are set to source, acquiring MRM signals of BAs derivatives
