Research on the fingerprint and three active components assay in Shenshuaining granules by HPLC / 药学实践杂志

ABSTRACT

Objective To establish the fingerprint spectrum and assay three active components (hesperidin, salvianolic acid B and chrysophanol) in Shenshuaining granule by HPLC method. Methods The chromatographic separation was achieved on SunFireTM C18 column with acetonitrile-0.1% formic acid aqueous solution as mobile phase. Gradient elution program was applied with flow rate of 1.0 ml/min, detection wavelength at 254 nm and the column temperature at 25 ℃. The fingerprint spectrum was established and three active components in Shenshuaining granule were assayed. Results There were 22 common peaks on the fingerprints after analyzing chromatograms from 10 batches of Shenshuaining granules. Good fingerprint similarities (≥0.9) between different batches and the control chromatogram were found. This method has great repeatability, stability and precision, which meets all the assay requirements. Conclusion A simple and reliable HPLC method was developed, which is suitable for the fingerprint establishment of Shenshuaining granules. It provides a method for the quality control of Shenshuaining granules.
