[Study on the chemical constituents in the volatile oils of the flowers of Tibetan medicine Rhododendron anthopogon].
OBJECTIVE
To study the chemical constituents of the volatile oils from the flowers of Rhododendron anthopogon D. Don.


METHODS
The volatile oils from the flowers of Rhododendron anthopogon D. Don were extracted by water steam distillation and its chemical constituents were separated and identified by GC-MS. The content of each constituent was determined by area normalizetion method.


RESULTS
Fifty peaks were separated and forty seven components were identified, which constituted about 97.44% of the total essential oils.


CONCLUSIONS
The main compounds are N-acetyl-1, 2, 3, 4-tetrahydro-isoquinoline (29.23%), 2-Ethoxypropane (12.47%), 3-Methyl-6-tert-butylphenol (10.83%), 3-Methyl-5-phenyl-isothiazole (6.38%), Diphenylamine (4.20%), N-ethyl-1, 2,3,4-tetrahydro-naphthalenamine (3.62%), Pentacosane (3.12%) and Tricosane (3.06%).
