[Simultaneous determination of six ingredients in Huoxiang Zhengqi oral liquid by UPLC].
To develop a UPLC method for the simultaneous determination of liquiritin, narirutin, hesperidin, ammonium glycyrrhetate, honokiol and magnolol in Huoxiang Zhengqi oral liquid.. A Zorbax Eclipse C18 column was used with the mobile phase of acetonitrile and 0. 05% phosphate acid by gradient elution at the detection wavelength of 220 nm. The flow rate was 0.42 mL x min(-1) and the column temperature was 30 degrees C.. The calibration curves were linear in the ranges of 0.001 7-0.034, 0.003 4-0.068, 0.006 4-0.128, 0.012 8-0.256, 0.003 2-0.064, 0.006 4-0.128 microg, respectively. The average recoveries were 103.3%, 98.39%, 98.29%, 102.1%, 98.45%, 102.2% with RSDs of 2.1%,1.0%, 0.50%, 2.3%, 0.9%, 2.0%, respectively.. The UPLC method was simple, rapid and accurate, it could be used for quality control of Huoxiang Zhengqi oral liquid.

Simultaneous determination of 12 chemical constituents in the traditional Chinese Medicinal Prescription Xiao-Yao-San-Jia-Wei by HPLC coupled with photodiode array detection.
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.

Determination of liquiritin, naringin, hesperidin, thymol, imperatorin, honokiol, isoimperatorin, and magnolol in the traditional Chinese medicinal preparation Huoxiang-zhengqi liquid using high-performance liquid chromatography.
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.
