[Rapid identification of Cortex moutan radicis and similar aromatic Chinese herbs by headspace gas chromatography].
OBJECTIVE
To establish the method for rapid identification of the quality of Cortex moutan radicis and similar aromatic Chinese herbs by headspace gas chromatography (HSGC).


METHODS
The constituents of headspace gas from Chinese herbs, such as Cortex moutan radicis,Radix cynanchi paniculati and root-bark of Paeonia lactiflora. were analyzed by HSGC.


RESULTS
The characteristic finger-print headspace chromatograms of these three drugs were different from one another. Cortex moutan radicis stored for 4 years under common conditions contained only traces of paeonol.


CONCLUSIONS
HSGC was simple, quick and accurate in identifying and controlling the quality of aromatic Chinese herbs.
