[GC-MS analysis of supercritical carbon dioxide extraction products from Rhodiola tibetica].
OBJECTIVE
To analyze the chemical constituents of supercritical carbon dioxide extraction products from Rhodiola tibetica.


METHODS
The chemical constituents were separated and identified by gas chromatography-mass spectrometry (GC-MS).


RESULTS
26 Components were identified, and their relative contents were determined by normalization method of area.


CONCLUSIONS
This study provides foundation for the exploitation of the resources of R. tibetica.
