[GC-MS analysis of essential oil of honeyed red ginseng].
OBJECTIVE
To investigate the constituents of essential oil of honeyed red ginseng, and provide scientific basis for its quality evaluation.


METHODS
The essential oil was extracted by hydrodistillation and separated by capillary GC. The chemical constituents were determined by normalization and were identified by MS.


RESULTS
One-hundred ninety-five chromatographic peaks were detected and among them 76 compounds were identified, which were 78.27% of the total essential oil.


CONCLUSIONS
The main constituents of the essential oil were sesquiterpenoids. Among identified compounds, 24 monoterpenoids and sesquiterpenoids were isolated from the essential oil of red ginseng for the first time.
