Popis: To investigate the pharmacokinetic characteristics of three phenylpropanoids (cinnamic acid, cinnamic alcohol and coumarin) in Ramulus Cinnamomi (GZ) and Ramulus Cinnamomi-Ephedrae Herba (MH) herb-couple (GZMH).Twelve male Sprague-Dawley rats were randomly and equally divided into the GZ and GZMH herb-couple groups. Blood samples were collected at 0, 0.08, 0.25, 0.5, 0.75, 1.5, 3, 4, 6, 8, 12, 24, 36 and 48 h after oral administration. The three phenylpropanoids in rat plasma were quantified using an ultra-performance liquid-chromatography with tandem mass spectrometry (UPLC-MS/MS) method for pharmacokinetic study.In GZMH group, the area under the curve (AUC), mean retention time (MRT) of cinnamic acid and coumarin were increased significantly (P0.01, respectively), and biological half-life (tThere were statistically significant differences in some pharmacokinetic parameters of the three compounds between GZ and GZMH groups, which meant that MH could affect the absorption and elimination of the three compounds.
