Study on HPLC fingerprint determination Huanglianjiedu Decoction / 中成药

ABSTRACT

Objective:To establish a HPLC fingerprint determination which could separate the main principles of alkaloids, flavonoids and iridoids in Huanglianjiedu Decoction. Methods: The HPLC method was used and chromatography conditions were C 18V column, binary or ternary solvent-delivery gradient elution and diode-array detector. Results: A HPLC fingerprint determination method was established, which could separate main principles of the three effective groups of Huanglianjiedu Decoction. Conclusion: The ingredients of traditional Chinese medicine consist of several effective groups with different chemicals and physical properties, compared with the plant standard extracts, further studies are required for establishing HPLC fingerprint.
