Laportea bulbifera extract is effective in resisting inflammation and shows a good therapeutic effect on rheumatoid arthritis in rats. However, the absorption characteristics of active components in L. bulbifera extract in Caco-2 cells are still unclear, which limits the in-depth development of L.

[Simultaneous determination of four components of Shuganning Injection in rat plasma by UPLC-MS/MS and its application to a pharmacokinetic study].

This study aims to reveal the pharmacokinetics of Shuganning Injection in normal rats. In this experiment,ultra-high performance liquid chromatography-electrospray-tandem mass spectrometry( UPLC-ESI-MS/MS) was used to establish an analytical method for simultaneous determination of chlorogenic acid,gardenioside,oroxylin A and baicalin in rat plasma. Then,the non-compartmental model( NCA) in Phoenix WinN onL in 6.
