In order to clarify the chemical composition of Tongmai Keli, a HPLC fingerprint was established, and the 22 peaks were characterized by LC-DAD-MS. The herbal sources of these peaks were assigned. The results implied that genistin 8-C-glucoside, puerarin, daidzein 8-C-apiosyl (1, 6)-O-glucoside, daidzin, and salvianolic acid B were the main constituents of in Tongmai Keli. Ten batches of Tongmai Keli produced by different pharmaceutical companies were analyzed. Although different batches contained similar compounds, the contents of major compounds were significantly different. The method established in this study could be used for the quality control of Tongmai Keli.

D053719 Tandem Mass Spectrometry A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.
