In vivo and in Vitro ComponentIdentification and Pharmacokinetic Analysis of Houpo Wenzhongtang Based on Rats with Deficiency-cold of Spleen and Stomach增强出版
To identify the chemical components of Houpo Wenzhongtang
in vivo
and
in vitro
and to analyze the pharmacokinetic properties of the index components in rats with deficiency-cold of spleen and stomach.
Method
2
The chemical components of Houpo Wenzhongtang was analyzed and identified by ultra performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS/MS). Six rats were randomly selected from 18 SD rats as the blank group, and the remaining rats were given lard and cold vinegar for a long time to construct a rat model with deficiency-cold of spleen and stomach. After successful modeling, the rats were randomly divided into the model group and Houpu Wenzhongtang group(13.5 g·kg
-1
, calculated as crude drug). The administration group was given the corresponding dose of Houpu Wenzhongtang by gavage, and the blank group
and the model group were given the same amount of distilled water by gavage. Enzyme-linked immunosorbent assay(ELISA) were used to measure gastrin(GAS) and motilin(MTL) levels in each group. At the same time, plasma samples were collected at different time points after administration, and blood-entry prototype components and metabolites of Houpo Wenzhongtang were analyzed by UPLC-Q-TOF-MS/MS. On this basis, plasma concentrations of magnolol, honokiol, alpinetin and hesperidin in Houpo Wenzhongtang were determined by ultra performance liquid chromatography coupled with triple quadrupole/linear ion trap mass spectrometry(UPLC-QTRAP-MS/MS), and the pharmacokinetic parameters were calculated using DAS 2.0 software.
Result
2
A total of 79 chemical components, including 44 flavonoids and 11 lignans, were identified in Houpo Wenzhongtang. Meanwhile, 18 blood-entry prototype components and 27 metabolites were identified, the main metabolic pathways of metabolites were glucuronidation, sulfation, oxidation and hydrolysis, and phase Ⅰ and phase Ⅱ were the two primary forms of metabolism. Pharmacokinetic results showed that among the four index components, the time to peak(
t
max
) values of magnolol and honokiol were consistent and exhibited similar drug metabolism characteristics, the
t
max
of alpinetin was the shortest, and the absorption rate was the fastest, which had the earliest peak plasma concentration levels, and hesperidin had the shortest mean residence time(MRT
0-
t
) and the highest metabolic rate in rats.
Conclusion
2
This study clarifies the blood-entry prototype components and their metabolites of Houpo Wenzhongtang in the rat model of deficiency-cold of spleen and stomach, and reveals the pharmacokinetic characteristics of the main active ingredients, which can provide a scientific basis for the study of pharmacodynamic material basis of this formula and its clinical application in treating the syndrome of deficiency-cold of spleen and stomach.
