[HPLC fingerprint chromatogram analysis of some Taraxacum in Henan province].
OBJECTIVE
To analyze the HPLC fingerprint chromatogram of some Taraxacum in Henan.


METHODS
Samples of different species, producing areas, harvest seasons and medicinal parts were determined by RP-HPLC. The chromatogram was evaluated by software of evaluating similarity.


RESULTS
The components of different species in Taraxacum were the same and could be substituted for each other. The contents of coffeic acid and chlorogenic acid in different producing areas were very different,which in fecund soil was better. The period of flowering and fruiting in Spring was the best gather period, and the components in different parts were different.


CONCLUSIONS
The quality of medicinal materal within Taraxacum should be controlled better by this method.
