[Analysis of essential oil from Mahonia duclouxiana].

To analyze the compositions of essential oil from Mahonia duclouxiana. The essential oil was extracted by steam distillation, its chemical components were analyzed by GC-MS, and principal component was confirmed by GC. 80 peaks were detected and 41 components have been identified, which made up more than 90% of total essential oil. The major component was 4-Terpineol (43.73%), the other high content components were alpha-Terpineol (5.23%), (Z)-3-Hexen-1-ol (4.78%), Linalool (4.04%), etc. The chemical components of essential oil of from Mahonia duclouxiana by GC-MS for the first time. This study provided science basis for further research development of Mahonia duclouxiana.
