Serum pharmacochemistry for tracking bioactive components by UPLC-Q-TOF-MS/MS combined chromatographic fingerprint for quality assessment of Sanziguben Granule.

To more reasonably and effectively control the quality of Sanziguben Granule, chromatographic fingerprinting and serum pharmacochemistry of this traditional Chinese medicine compound were performed. A comprehensive comparison and evaluation of 15 batches of Sanziguben Granule was successfully conducted by using high performance liquid chromatography (HPLC) fingerprint analysis. After administering a set amount of Sanziguben Granule orally to rats, blood samples were collected and tested 4 times at intervals of 30min, 1h, 2h, and 4h using UPLC-Q-TOF-MS/MS.
