Abstract:
The chemical components of essential oil from Alpinia oxyphylla Miq in Guangdong province was extracted by steam distillation extraction (SD) and supercritical fluid CO2 extraction (SFE-CO2). The yields of the oil by the two methods were compared, and the chemical components in the oil achieved by different extraction methods were also analyzed by GC-MS. It was found that the main components of the essential oil obtained with the two methods were similar.
