[Analysis of chemical constituents of the volatile oil from flowers of Oyster Rhoeo by GC/MS].
OBJECTIVE
To analyze the chemical constituents of the volatile oil from the flowers of Oyster Rhoeo.


METHODS
The volatile oil from the flower of Oyster Rhoeo was extracted by steam distillation and its chemical constituents were analyzed by GC/MS technique.


RESULTS
All 20 compounds which relative content was greater than 0.3% were identified, accounting for 90.24% of the volatile oil.


CONCLUSIONS
The major constituent of the volatile oil is nonaldehyde (25.72%), the other main constituents are hexadecanoid acid (22.79%), nonanoic acid (18.94%), dodecanoic acid (7.72%), isovanillin (2.84%), heptanoic acid (2.20%), octanoic acid (1.89%) and linoleic acid (1.71%), respectively.
