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.

Introduction: A rapid, sensitive and convenient ultra-performance liquid chromatography with tandem mass spectrometric detection (UPLC-MS/MS) method has been validated and applied to the simultaneous determination of kirenol, rosmarinic acid and caffeic acid after oral administration of the extract of Manxingshizhen preparation in rat plasma. Materials and Methods: Puerarin was selected as the internal standard (IS). The plasma sample preparation was pretreated by liquid-liquid extraction of the mixture with ethyl acetate. All analytes were simultaneously detected in multiple reaction monitoring (MRM) mode via both the positive electrospray ionization (ESI+) and negative electrospray ionization (ESI). In the experiment, all calibration curves revealed good linearity (r > 0.999). The LLOQ were between 0.80-2.00 ng/mL, respectively. Besides, the intra-day and inter-day precision ranged from 6.4 to 13.8%, respectively. Moreover, the accuracy was within - 11.4% and 12.8% for all the QC levels of all analytes. The extraction recoveries of the analytes and IS in plasma at three concentration levels ranged from 88.5 to 103.2%, moreover, the matrix effects of all the analytes and the IS were found to be satisfied with the acceptable range of 89.8%-101.7%. Meanwhile, the RSD values of stability met the requirement of not more than 15%. Furthermore, the pharmacokinetic parameters of three compounds were analyzed using concentrationtime profiles. Conclusion and Results: Plasma concentrations of the three compounds were determined up to 24 h after oral administration, and their pharmacokinetic parameters were in agreement with previous studies. The validated method was successfully applied in a pharmacokinetic study in rat plasma after oral administration of Manxingshizhen preparation.

Huang-Lian Jie-Du decoction (HLJDD) has been used to treat cardiovascular and cerebrovascular disease for many years in China. Currently, the determination of effect components in HLJDD is focusing either on the formula or on the extract, while quantification of that in biological samples is scarce, especially simultaneous determination of multicomponent. In this paper, a rapid, specific, and sensitive ultra-high performance liquid chromatography-tandem mass spectrometry method was developed and fully validated for the simultaneous determination of seven main active constituents, i.e., baicalin, baicalein, wogonoside, wogonin, berberine, palmatine, jatrorrhizine in rat plasma. The method was also successfully applied to a quantitative study after oral administration of HLJDD at different doses of 1.5, 3, and 6 g/kg body weight to high fat-induced atherosclerosis rats. The analytes were detected by ESI source and multiple reactions monitoring (MRM) using positive scanning mode. The blood was collected from the abdominal aorta of rats at predetermined time and preprepared with icariin and tetrahydropalmatine as internal standards (IS). Sample preparation was achieved by protein precipitation (PPT). The validation parameters (linearity, sensitivity, intra-/interday precision and accuracy, extraction recovery, and matrix effect) were within acceptable ranges, and biological extracts were stable during the entire storing and preparing process. And the result of determination of HLJDD-containing plasma, baicalin, baicalein, wogonoside, and wogonin could be highly detected in a dose-dependent manner while berberine, jatrorrhizine, and palmatine were determined in a very low level and in a dose-independent mode. Thus, the established method was sensitive enough and successfully applied to the determination of seven effective components in plasma taken from 24 high fat-induced atherosclerosis rats after oral administration of three dosages of HLJDD.
