ETHNOPHARMACOLOGICAL RELEVANCE: Tianshu capsule (TSC) is a traditional Chinese medicine (TCM) preparation and has significant clinical effect on migraine. The composition characteristics of TSC formula are worth exploring for the treatment of migraine.
AIM OF THE STUDY: Identify the compounds in vivo after oral administration of TSC, Gastrodin (GAS), ferulic acid, senkyunolide G and senkyunolide I in the blood of healthy and migraine rats were used as representative compounds for time-dependent processes investigation. And we focus on explaining the characteristics of TSC treatment on migraine from a pharmacokinetic perspective.
MATERIALS AND METHODS: In this study, Ultra-high performance liquid chromatography with Orbitrap tandem mass spectrometry (UPLC-Orbitrap-MS/MS) system were used to detect the compounds in rat plasma and brain after oral administration of TSC. A sensitive, selective and reliable ultra-performance liquid chromatography coupled with triple quadrupole mass spectrometry (UPLC-TQ-MS/MS) system method was established for the simultaneous quantitative analysis of multi-components and evaluate the pharmacokinetic behavior of four main compounds.
RESULTS: A total of 46 compounds were significantly identified in vivo of rat, including 35 compounds in plasma, 7 compounds only in brain and 4 compounds both in plasma and brain. The quantitative method has been confirmed to be feasible for multi-components content determination, pharmacokinetic parameters indicated that the four compounds absorbed into blood rapidly, and senkyunolide I also cross the blood-brain barrier (BBB) quickly into brain. GAS has relatively high concentrations in plasma, and the parameters AUC0-t, CLz/F displayed significant differences between the normal and migraine rats. And the AUC0-t and Cmax of GAS and ferulic acid exhibited dose-dependent way.
CONCLUSIONS: we added compounds for the pharmacokinetic study of TSC, providing powerful help for clinical medication in the treatment of migraine.
