[Chemical pattern recognition for HPLC fingerprint analysis of Flos Lonicerae Japonicae in different collecting time].
OBJECTIVE
To compare HPLC fingerprint of Flos Lonicerae Japonicae in different collecting time for determining harvest.


METHODS
The data from RP-HPLC were analyzed by similarity evaluation, principle component analysis and system cluster analysis.


RESULTS
The content of chemical composition of Flos Lonicerae Japonicae were vaiance on collecting time. The best harvesting time was the erbai period.


CONCLUSIONS
The study offers the basis of controlling the quality of Flos Lonicerae Japonicae and the realization of good agricultural practice.
