[GC-MS analysis of chemical constituents of volatile oil from flowers of Rhododendron mucronatum].
OBJECTIVE
To analyze the chemical constituents of volatile oil from flowers of Rhododendron mucronatum.


METHODS
The volatile oil was extracted by water-steam distillation and analyzed by GC-MS.


RESULTS
Forty-nine compounds, which occupied 79.55% of total constituents, were identified. The major constituents were linalool, beta-eudesmene, phytol, benzyl benzoate, benzyl salicylate and nonyl aldehyde.


CONCLUSIONS
The chemical constituents of volatile oil, which contain many bioactive constituents, are mainly composed of terpenes, esters, and alkanes.
