![عکس صفحه اول مقاله: Determination of mangiferin in rat plasma by liquid–liquid extraction with UPLC–MS/MS Determination of mangiferin in rat plasma by liquid–liquid extraction with UPLC–MS/MS](/preview/png/1223572.png)
An ultra-performance liquid chromatography tandem mass spectrometry (UPLC–MS/MS) method employing electrospray ionization (ESI) has been developed for the determination of mangiferin in rat plasma using diphenhydramine as the internal standard (IS). Liquid–liquid extraction (LLE) was used for sample preparation and the analysis was achieved with gradient elution on C18 reversed phase column. The method was validated over the concentration range 0.02–5.0 μg/mL for oral administration and 0.4–100 μg/mL for intravenous administration. The intra-day and inter-day precision of mangiferin expressed as RSD < 15% and the accuracy (RE) did not exceed 15%. This validated method is a novel technique for sample preparation and quantitation, which was successfully applied to estimate the bioavailability of mangiferin.
