Aims: Pharmacokinetic Study of Salviae Miltiorrhizaeand Ligustrazine Hydrochloride injection. For the evaluation of mechanism of action, safety and clinical rational use of Salviae Miltiorrhizae and Ligustrazine Hydrochloride injection. Background: Salviae Miltiorrhizae and Ligustrazine Hydrochloride injection is a compound preparation consisted of Salvia Miltiorrhiza extract and ligustrazine hydrochloride for the treatment of cardiovascular and cerebrovascular diseases in China. Methods: Plasma samples were precipitated with methanol, which was spiked with ascorbic acid and the supernatant was separated on a Waters Cortecs C18 column, by using a gradient mobile phase system of acetonitrile-water containing 0.05% formic acid (v/v). For internal standards, puerarin was selected for the five salvianolic acids, while isofraxidin was used for ligustrazine hydrochloride. Besides, electrospray ionization in negative mode and multiple-reaction monitoring were used to identify and quantify the five salvianolic acids, whereas ligustrazine hydrochloride was quantified at 310 nm using the diode array detector. Results: Noticeably, all calibration curves showed good linearity (R2>0.99) over the concentration range, with a lower limit of quantification between 0.00411 and 0.0369μg/mL for salvianolic acids, and 1.74 μg/mL for ligustrazine hydrochloride. Next, the precision of the developed method was evaluated by intra-and inter-day assays, and the percentage of relative standard deviation was within 10%. Although the extraction efficiency of some salvianolic acids were not very satisfactory, the sensitivity of the analytical method met the analysis requirements of rat plasma samples. Moreover, the validated method was successfully applied to a pharmacokinetic study of Salviae Miltiorrhizae and Ligustrazine Hydrochloride injection in the rat model. Conclusion: Linear pharmacokinetic characteristics were observed for the six active ingredients after intravenous infusion administration in rats, within the dose range examined here. In summary, our study proposed a HPLC-DAD-MS/MS method in the simultaneous determination of multiple ingredients, and demonstrated its applicability in pharmacokinetic studies.

A simple and sensitive HPLC method was developed for simultaneous determination of danshensu (DSS), rosmarinic acid (RA), lithospermic acid (LA), salvianolic acid B (SAB), and hyperoside (HP) in rat plasma. This method validated was successfully applied to the pharmacokinetic study of the main active ingredients after oral administration ofRadix Salviae Miltiorrhizaeextract (SME), hawthorn extract (HTE), and a combination of both extracts (2.5 : 1) to rats. The results indicated that there have been great differences in pharmacokinetics between a single extract and a combination of both extracts. A combination of both extracts can enhance their bioavailabilities and delay the elimination of SAB and DSS in rats.

Background: Apigenin, a natural plant flavone, has been shown to possess a variety of biological properties. Objective: In this report, a highly selective and sensitive LC-MS/MS method was developed and validated for the determination of apigenin in rat plasma. Methods: Analysts were separated on the HSS T3 column (1.8 μm 2.1×100 mm) using acetonitrile and 0.1% formic acid in 2 mM ammonium acetate buffer at a supply rate of 0.200 mL/min as eluent in gradient model. Results: Plasma samples were treated by protein precipitation using acetonitrile for the recovery ranging from 86.5% to 90.1% for apigenin. The calibration curves followed linearity in the concentration range of 0.50-500 ng/mL. The inter-day and intra-day precisions at different QC levels within 13.1% and the accuracies ranged from -10.6% to 8.6%. Conclusion: The assay has been successfully applied to the pharmacokinetic study of apigenin in rats.
