RÉSUMÉ

Objective: To establish a UPLC-PDA-ELSD method for the fingerprint of Xiaokeqing Granules (XG) and to determine the contents of neomangiferin, mangiferin, timosaponin BII, palmatine, and berberine so as to provide the basis for the quality control of XG. Methods: The chromatographic fingerprints were determined by UPLC-PDA-ELSD using mangiferin and timosaponin BII peaks as the reference peaks, 23 PDA and 10 ELSD common peaks were selected, and the digital quantitative fingerprint of XG was established. Using the third systematic quantified fingerprint method, the quality levels of 28 batches of XG were assessed. The contents of neomangiferin, mangiferin, timosaponin BII, palmatine, and berberine in the 28 batches of samples were determined using external st andard method. Results: Twenty batches of XG were identified as qualified and eight batches were unqualified, in which there were differences in the five main consitituents. The quantitative results were consistent with the fingerprint. Conclusion: The method is accurate, stable, and simple, which could be applied to the quality control of XG.
