Simultaneous determination of four bioactive constituents in Liuwei Dihuang Pills by micellar electrokinetic chromatography. Journal of pharmaceutical and biomedical analysis, 2007, Sep-03, Volume: 44, Issue:5 A micellar electrokinetic chromatography (MEKC) method for the simultaneous determination of four bioactive constituents (morroniside, loganin, paeoniflorin and paeonal) in the Chinese patent medicine Liuwei Dihuang Pills is established. A carrier composed of 0.2M boric acid, 0.02 M sodium dodecyl sulfate (SDS) and 5% acetonitrile (pH was adjusted to 10.5 with 0.1 M NaOH) is found to be the most suitable electrolyte for this separation. The four constituents in Liuwei Dihuang Pills can be easily determined within 16 min. Optimization of separation is realized with the univariate approach by studying the effects of four factors relevant to run buffer on migration times. Topics: Acetonitriles; Benzoates; Boric Acids; Bridged-Ring Compounds; Buffers; Chloramphenicol; Chromatography, Micellar Electrokinetic Capillary; Drug Carriers; Drugs, Chinese Herbal; Glucosides; Glycosides; Humans; Hydrogen-Ion Concentration; Iridoids; Molecular Structure; Monoterpenes; Reference Standards; Reproducibility of Results; Sodium Dodecyl Sulfate; Time Factors	2007
Determination of paeonol and paeoniflorin in Chinese medicine Cortex Moutan and 'Shuangdan' granule by micellar electrokinetic capillary chromatography. Journal of pharmaceutical and biomedical analysis, 2006, Mar-18, Volume: 40, Issue:5 An easy, simple and rapid micellar electrokinetic capillary chromatography (MEKC) method was developed for the separation of two active components paeonol (PN) and paeoniflorin (PF) within 7 min. Capillary electrophoresis (CE) was performed using a 50.0 cm (42.0 cm to the detector window) x 75 microm i.d. fused-silica capillary. The optimal running buffer containing 10mM borate and 25 mM SDS at pH 9.54 was employed. The applied voltage 15 kV and the temperature 25 degrees C was used in CE separation. The linearities between peak areas and the concentrations of the analytes were investigated, and they exhibited excellent linear behavior over the investigated concentration ranges (R(2): 0.9945 for PN and 0.9992 for PF). The method was successfully applied to the determination of these two components contained in Cortex Moutan and 'Shuangdan' granule. The average recoveries ranged between 97.6 and 105.3% for PN and 95.3 and 106.1% for PF, respectively. Topics: Acetophenones; Benzoates; Bridged-Ring Compounds; Buffers; Calibration; Chromatography, Micellar Electrokinetic Capillary; Drugs, Chinese Herbal; Glucosides; Hydrogen-Ion Concentration; Indicators and Reagents; Monoterpenes; Paeonia; Reference Standards; Reproducibility of Results; Sodium Dodecyl Sulfate	2006
