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.
Conclusion: 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.
