Abstract: The quality of Hemerocallis citrina Baroni was studied by character identification,content determination and fingerprinting in this paper.Firstly,H.citrina was wetted dampness from different areas,and each structure was measured to gain data,which were made the correlation analysis.Secondly,the fingerprints and the main components of H.citrina were determined by HPLC,and similarity evaluation and principal component analysis of fingerprints for each batch were carried out.The HPLC fingerprints of H.citrina were set up in the research,in which 45 common peaks were determined;the four common peaks were identified according to the reference standard among them,and its content was measured.The results showed the external morphology of H.citrina had significant differences,and a certain correlation with the origin,altitude,latitude and longitude,etc.The results can provide a reliable evaluation method for the quality control of H.citrina.

Key words: Hemerocallis citrina, macroscopical identification, HPLC fingerprint
