Simultaneous determination of naringin, hesperidin, neohesperidin, naringenin and hesperetin of Fractus aurantii extract in rat plasma by liquid chromatography tandem mass spectrometry.
    Journal of pharmaceutical and biomedical analysis, 2012, Jan-25, Volume: 58

    A liquid chromatography tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous determination of naringin, hesperidin, neohesperidin, naringenin and hesperetin in rat plasma, using liquiritin as the internal standard. Plasma samples extracted with a solid-phase extraction procedure were separated on a Zorbax SB-C18 analytical column (2.1 mm × 150 mm, 5 μm) and detected by electrospray ionization (ESI) in multiple reaction monitoring (MRM) mode. The calibration curves were linear over the range of 3.0-600 ng/ml for naringin, 0.5-100 ng/ml for hesperidin, 3.5-700 ng/ml for neohesperidin, 5.0-1000 ng/ml for naringenin and hesperetin, respectively. The lower limits of quantification were 0.5 ng/ml for naringin, hesperidin, naringenin and hesperetin, and 0.35 ng/ml for neohesperidin. Intra- and inter-day precision (RSD%) was less than 15% and accuracy (RE%) ranged from -3.3% to 4.8%. The validated method was successfully applied to investigate the pharmacokinetics of the major flavanones of Fructus aurantii extract after oral administration to rats.

    To develop a RP-HPLC method for simultaneous determination of liquiritin, naringin, hesperidin and glycyrrhizic acid in extraction of Wendan formula.. DIKMA Diamonsil(2)-C18 column (4.6 mm x 250 mm, 5 microm) was used at 25 degrees C with the mobile phase of acetonitrile-0.1% phosphatic acid in a gradient manner. The flow rate was set at 1.0 mL min(-1). The detection wavelength was 237, 283 nm.. The linear responses ranged from 0.0199-0.1191 microg for liquiritin (r = 0.9997, n = 6), 0.1800-1.0800 microg for naringin (r = 0.9997, n = 5), 0.1455-0.8730 microg for hesperidin (r = 0.9998, n = 6), 0.0393-0.2355 microg for monoammonium glycyrrhizinate (r = 0.9997, n = 6), respectively. The average recoveries were 97.7% with RSD 1.5% for liquiritin, 97.7% with RSD 2.0% for naringin, 97.1% with RSD 2.0% for hesperidin and 98.5% with RSD 1.9% for glycyrrhizic acid, respectively.. The method is quick, simple and repeatable for simultaneous determination of liquiritin, naringin, hesperidin and glycyrrhizic acid in extraction of Wendan formula.

[Identification of the metabolites of Sinisan extract in rat plasma, urine, feces and bile after intragastric administration].
    Yao xue xue bao = Acta pharmaceutica Sinica, 2011, Volume: 46, Issue:11

    Sinisan is a widely used traditional Chinese medicine (TCM) in treating various diseases; however, the in vivo metabolic profile of its multiple components remains unknown. In this paper, ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) was applied to identify the metabolites of Sinisan extract in rat plasma, urine, feces and bile after intragastric administration. Using MS(E) and mass defect filter techniques, 41 metabolites of 10 parent compounds (naringin, naringenin, hesperidin, neohesperidin, liquiritin, liquiritigenin, glycyrrhizic acid, glycyrrhetinic acid, saikosaponin a and saikosaponin d) were detected and tentatively identified. It was shown by our results that these compounds was metabolized to the forms of hydroxylation, glucuronidation, sulfation, glucuronidation with sulfation and glucuronidation with hydroxylation in vivo.

Simultaneous determination of 12 chemical constituents in the traditional Chinese Medicinal Prescription Xiao-Yao-San-Jia-Wei by HPLC coupled with photodiode array detection.
    Journal of pharmaceutical and biomedical analysis, 2008, Dec-15, Volume: 48, Issue:5

    An HPLC-photodiode array (PDA) detection method was established for the simultaneous determination of 12 components in Xiao-Yao-San-Jia-Wei (XYSJW): geniposide, puerarin, paeoniflorin, ferulic acid, liquiritin, hesperidin, naringin, paeonol, daidzein, glycyrrhizic acid, honokiol, and magnolol. These were separated in less than 70 min using a Waters Symmetry Shield RP 18 column with gradient elution using (A) acetonitrile, (B) water, and (C) acetic acid at a flow rate of 1 ml/min, and with a PDA detector. All calibration curves showed good linear regression (r(2)>0.9992) within the test ranges. The method was validated for specificity, accuracy, precision, and limits of detection. The proposed method enables in a single run the simultaneous identification and determination for quality control of 12 multi-structural components of XYSJW forming the basis of its therapeutic effect.

    Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan, 2006, Volume: 126, Issue:11

    High-performance liquid chromatography was employed to determine the contents of the eight marker components liquiritin, naringin, hesperidin, thymol, imperatorin, honokiol, isoimperatorin, and magnolol in the traditional Chinese medicinal preparation Huoxiang-zhengqi liquid. The separation was performed on a C(18) column by stepwise gradient elution with water-methanol-acetonitrile (0.01 min, 68:30:2; 20 min, 60:38:2; 50 min, 34:64:2; 65 min, 34:64:2; 75 min, 28:70:2; 85 min, 68:30:2) as the mobile phase at a flow rate of 1 ml/min, with UV detection at 283 nm. Eight regression equations showed good linear relationships between the peak area ratio of each marker to internal standard and amounts. The recoveries of the markers listed above were 97.4, 98.5, 97.4, 98.6, 97.8, 99.2, 97.0, and 97.5%, respectively. The repeatability and reproducibility (relative standard deviation) of the method were less than 2.2 and 3.0%, respectively.
