Development of the fingerprints for the quality evaluation of Viscum coloratum by high performance liquid chromatography

A high-performance liquid chromatography coupled ultraviolet (HPLC-UV) method was developed for a chemical fingerprint analysis of Viscum coloratum. Eighteen peaks were selected as the common peaks and Homoeriodictyol-7-O-β-D-apiosiyl-(1→2)-β-D-glucoside was used as a reference.The relative areas of common peaks were used for hierarchical clustering analysis and similarity calculation.Thirty-seven samples collected from different sources were classified imo five groups.The similarities of 21 batches Viscum coloratuma samples were beyond 0.90.The results obtained suggest that the chromatographic fingerprint can efficiently identify Viscum coloratum.Additionally,the fingerprints can then be used to evaluate the correlation between Viscum coloratum and hosts.
