Pharmacokinetic Comparisons of Eight Active Components from Raw Farfarae Flos and Honey-Processed Farfarae Flos after Oral Administration in Rats by UHPLC-MS/MS Approaches.

ABSTRACT: Farfarae flos (FF) is widely used for cough over thousands of years in China, but little is known about their pharmacokinetics properties. This study was aimed to establish a rapid and accurate ultraperformance liquid chromatography with triple-quadrupole tandem mass spectrometry method for compare pharmacokinetics studies of eight active compounds after oral administration between raw and honey-processed farfarae flos extracts. Optimum separation was performed on a Thermo Hypersil GOLD C18 column (100?mm?×?2.1?mm, 1.9?µm particles size) with a gradient elution of acetonitrile as mobile phase A and 0.3% formic acid aqueous solution as mobile phase B. The flow rate was set as 0.3?mL/min and separated for 34.0 minutes. Electrospray ionization in the negative ion mode and selected reaction monitoring were used to identify and separate active components. The results met the acceptance criteria and showed that this method exhibited good linear, precision, accuracy, and stability. The extraction recoveries ranged from 81.54% to 104.48%, and the matrix effects ranged from 81.94% to 103.02%. These results show that the validated method could be successfully applied to evaluate the pharmacokinetic study in rats after oral administration of raw farfarae flos (R-FF) and honey-processed farfarae flos (H-FF).

Project description:An accurate and precise liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method was developed and validated for the pharmacokinetic study of epiprogoitrin and progoitrin, a pair of epimers that can be deglycosylated to epigoitrin and goitrin, respectively. These analytes were administered intravenously or intragastrically to male Sprague-Dawley rats, and the influence of 3(R/S)-configuration on the pharmacokinetics of both epimers in rat plasma was elucidated. The analytes and an internal standard (i.e., sinigrin) were resolved by LC-MS/MS on a reverse-phase ACQUITY UPLC™ HSS T3 column equilibrated and eluted with acetonitrile and water (0.1 % formic acid) at a ?ow rate of 0.3?mL/min. Quantitation was achieved by applying the multiple reaction monitoring mode, in the negative ion mode, at transitions of m/z 388 ? 97 and m/z 358 ? 97 for the epimers and sinigrin, respectively. The method demonstrated good linearity over the concentration range of 2-5000?ng/mL (r > 0.996). The lower limit of quantification for epiprogoitrin and progoitrin was 2?ng/mL. The interday and intraday accuracy and precision were within ±15 %. The extraction recovery, stability, and matrix effect were demonstrated to be within acceptable limits. The validated method was thus successfully applied for the pharmacokinetic study of both the epimers. After the rats received the same oral dose of the epimers, the pharmacokinetic profiles were similar. The maximum plasma concentration (Cmax) and AUC values of epiprogoitrin were a bit higher than those of progoitrin, whereas the pharmacokinetic behaviours of the epimers were obviously different upon intravenous administration. The Cmax and AUC values of epiprogoitrin were approximately three-fold higher than those of progoitrin, and the half-life of progoitrin was much shorter than that of epiprogoitrin. The oral bioavailability of progoitrin was 20.1 %-34.1 %, which is three times higher than that of epiprogoitrin.
