Objective: To develop a method for quality control of effective fraction in Qi-Xue-Bing-Zhi decoction, a traditional Chinese medicine (TCM).
Method: PF samples, effective fraction from Qi-Xue-Bing-Zhi decoction, were used as example, and a HPLC assay for chemical fingerprint and quantitative analysis was established.
Result: The contents range of Paeoniflorin (PE), Naringin (NG) and Neohesperidin (NH) in effective fractions were changed from 12.5%-16.0%, 8.4%-12.4%, 12.8%-15.3%, and their average contents were (14.7 +/- 1.1)%, (10.6 +/- 1.2)%, (14.2 +/- 0.8)% (n = 10), respectively. The fingerprints of PF samples showed 25 common peaks, and the fingerprint similarity for PF samples were all above 99.00% by comparing with the standard chromatogram.
Conclusion: The method reported could be used effectively for the quality control of effective fraction from TCM.
