[Vectorial angle method for studying on GC fingerprint of naphtha in Alpinia officinarum Hance].
OBJECTIVE
To establish GC quality analysis and GC fingerprint spectrum of naphtha in Alpinia officinarum Hance.


METHODS
The naphtha in Alpinia officinarum Hance was extracted and analyzed by GC to establish the fingerprint spectrum. The results were analyzed by similarity grade calculate method to compare the fingerprint difference of Alpinia officinarum Hance.


RESULTS
The GC fingerprint spectrum of Alpinia officinarum Hance were established. It consisted of 11 peaks. The GC spectrum results were analyzed by similarity grade calculate method which can divide Alpinia officinarum Hance into various habitats.


CONCLUSIONS
The fingerprint spectrum can be used to distinguish Alpinia officinarum Hance and to evaluate its quality.
