The composition of PF-GPD was analyzed by SHIMADZU API 4000 LC/MS/MS system equiped with SHIMADZU VP-ODS column (4. 6 mm × 150 mm). The mobile phase A was 1% formic acid, mobile phase B was acetonitrile, the gradient elute condition was 0–5 min 45% mobile phase B, flow velocity is 0.5 mL/min, and the column temperature was 40 °C. The total ion chromatography of PF-GPD and extract ion chromatography of the L-leucine, L-lysine and L-valine were shown in picture a, b, c and d, respectively
