ABSTRACT
Objective:
To establish an HPLC-ELSD method for simultaneous determination of astragaloside IV, ferulic acid, paeoniflorin, glycyrrhizic acid, vaccarin, naringin, neohesperidin, and platycodin D in Buxue Shengru Granules (BSG).Methods:
The analysis of methanol extract of this drug was performed on a Diamonsil C18 (250 mm × 4.6 mm, 5 μm) with the mobile phase comprising of 0.1% formic acid aqueous solution-acetonitrile. Flow rate was 1 mL/min and column temperature was 30 ℃. The samples were tested on Evaporative Light-scattering Detector with drift tube temperature of 40 oC.Results:
The analysis permitted very good separation of eight constituents within 52 min. The linearity ranges of the eight constituents were 62.5-1 250.0 μg/mL (r > 0.995 0). The average recoveries of eight constituents in the samples were in the range of 95.51%-99.47%, and the RSD ranged from 0.31% to 3.70%. Intraday and interday precisions RSD of the peak areas of the eight components were less than 3%; The repeatability RSD of each component ranged from 0.94% to 2.11%; Eight components had good stability within 18 h, and the concentration RSD of each component ranged from 0.98% to 2.86%. The content of vaccarin, paeoniflorin, ferulic acid, naringin, neohesperidin, platycodin D, astragaloside IV, and glycyrrhizic acid were 0.550 7-0.584 3, 19.657 9-19.952 1, 0.350 5-0.384 7, 18.794 7-19.557 3, 12.124 7-12.414 2, 0.610 7-0.631 3, 0.238 8-0.274 3, and 2.750 4-2.852 2 mg/g, respectively.Conclusion:
This simple and accurate method can be used for the rapid quality control of BSG.
