ABSTRACT

Objective:

A comprehensive and in-depth analysis method for identification of chemical constituents in Suanzaoren Tang granules was established.

Method:

Ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) was employed with the mobile phase of 0.1% formic acid aqueous solution (A)-acetonitrile (B) for gradient elution (0-8 min, 5%-17%B; 8-10 min, 17%B; 10-11 min, 17%-18%B; 11-12 min, 18%-20%B; 12-17 min, 20%-23%B; 17-22 min, 23%-33%B; 22-30 min, 33%-60%B; 30-32 min, 60%-100%B; 32-36 min, 100%B), the flow rate of 0.3 mL·min<sup>-1</sup> and electrospray ionization (ESI). High quality MS/MS data were scanned in positive and negative ion modes with scanning range of <italic>m</italic>/<italic>z</italic> 50-1 500. The local database of the chemical components from different Chinese medicines in Suanzaoren Tang granules was established by SCIEX OS software. Then the chemical components in Suanzaoren Tang granules were characterized by matching with the local database and comparing with the reference substance and literature information.

Result:

A total of 134 compounds were characterized and identified under positive and negative ion modes, mainly including flavonoidstriterpenoids, phthalides, steroidal saponinsalkaloids and organic phenolic acids. In addition, the sources of Chinese medicines for all compounds identified in Suanzaoren Tang granules were assigned. Among them, 41 were from Ziziphi Spinosae Semen, 11 were from Poria, 22 were from Anemarrhenae Rhizoma, 28 were from Chuanxiong Rhizoma and 35 were from Glycyrrhizae Radix et Rhizoma.

Conclusion:

The method can be used to identify the chemical constituents in Suanzaoren Tang granules systematically, quickly and accurately, which can provide a new strategy for the rapid and accurate identification of other Chinese patent medicines.
