[Study on HPLC fingerprint of SFE ginger extract].
OBJECTIVE
To establish a standard fingerprint of SFE ginger extract.


METHODS
HPLC method was used with elite hypersil ODS column (4.6 mm x 25 cm, 5 microm); mobile phase was acetonitrile--0.1% phosphoric acid solution mixture in gradient mode with a flow rate of 1.0 mL x min(-1); detection length was 280 nm; column temperature was 25 deggrees C.


RESULTS
The similarity of every fingerprints was bagger than 0.9 in precision tests, stability tests and repeation tests.


CONCLUSIONS
The method can be used for the quality control of SFE ginger extract.
