ABSTRACT

OBJECTIVE: To rapidly identify chemical components of Zhitong huazheng capsules (shorted for “ZTHZC”), and to provide reference for further elucidating the pharmacodynamic material basis and overall quality control. METHODS: UPLC-Q-TOF/MS method was adopted to separate the chemical components of ZTHZC. By reviewing literatures that related to chemical components of ZTHZC and its single Chinese traditional medicinal crops, the chemical structure of the chemical components was saved into a .mol format file, and supplemented the UNIFI database. The chemical constituents of ZTHZC were qualitatively analyzed by UNIFI database screening, and validated according to their precise molecular mass, characteristic ions, neutral loss, secondary mass spectrometry cleavage, chromatographic retention behavior, combined reference information and literature reports. RESULTS: A total of 70 chemical components were identified in this experiment, including 38 organic acids and organic acid esters, 8 alkaloids, 9 flavonoids, 5 triterpenoid saponins, 5 aldehydes, 2 ketones, 1 quinone, 1 polyacetylene and 1 monoterpenoid. CONCLUSIONS: This study provides a rapid detection and identification method for chemical components of ZTHZC, and also provides a scientific basis for the clarification of ZTHZC’s quality control and pharmacodynamics.

ABSTRACT

To identify and analyze the constituents in rat serum after oral administration of Zhitong Huazheng capsule (ZTHZC), and provide a reference for its further research on pharmacodynamics material basis. Female Wistar rats were selected as experimental animals, and received intragastric administration of ZTHZC at a dose of 1.5 g·kg⁻¹. After the serum samples were collected, the absorbed prototype components in rat serum were identified and analyzed by using ultra-high performance liquid chromatography-quadrupole-time-of-flight/mass spectrometry (UPLC-Q-TOF/MS) combined with multivariate statistical analysis.The results showed, a total of fifteen absorbed constituents were identified, all of which were prototype components, including Danshensu, salvianolic acid A, B, C, D, 9,12-dihydroxy-15-nonadecanoicacid, linoleic acid, ethyl palmitoleate, tetrahydropalmatine, fumarate A, astragaloside A, astragaloside II, saponin, locustin and luteolin. This experiment showed that these fifteen components absorbed into blood may be the potential bioactive components in ZTHZC, providing a scientific basis for clarifying its material basis in pharmacodynamics.
