[Analysis of the chemical constituents of essential oil from Chimonanthus zhejiangensis by GC-MS].

OBJECTIVE: To analyze the chemical constituents of the essential oil from Chimonanthus zhejiangensis. METHODS: Steam distillation was employed to extract volatile compounds of essential oil from Chimonanthus zhejiangensis. Volatile compounds of essential oil were isolated and identified by capillary GC-MS-DS. RESULTS: 37 components were separated and 33 components were successfully identified. CONCLUSION: The main components were 1,4-Cineole (46.20%), 1,5,9-Undecatriene, 2,6, 10-trimethyl-, (Z)-(9.71%), Cyclohexane, 3,4-bis (1-methylethenyl) -1, 1-dimethyl-(7.42%), Trioctylamine (6.44%), alpha-Terpinyl propionate (4.01%), alpha-Pinene (3.92%).
