Analysis on volatile oils from different parts of Alpinia zerumbet by GC-MS / 中成药

AIM:To analyze the chemical constituents of essential oils from three different parts of Alpinia zerumbet.METHODS:The oils were extracted by steam distillation.The chemical compounds were separated and identified by GC-MS.The relative content of each component was determined by area normalization.RESULTS:Fifty-five,sixty-seven,and sixty-six compounds from seed pericarp and capsule of Alpinia zerumbet were identified respectively.The ratios of identification of total compounds were 99.86%,95.83% and 95.52%,respectively.CONCLUSION:There are some differences among three different parts of Alpinia zerumbet.It provides the research base for advanced research and development.
