UPLC-MS/MS analysis of ZBDHD in negative ionization mode. The identified main appearing peaks with retention time between 0.5 and 12 min in total ion current (TIC) chromatogram were numbered from 1 to 5. And the specific ingredients of ZBDHD were marked from A to J. The m/e, retention time, and identification of peaks are listed in Table 2.
