Study on the extraction methods of essential oil from Cortex Cinnamomi
This paper mainly studied on the essential oil components from Cortex Cinnamomi by supercritical fluid CO2 extraction (SFE-CO2), steam distillation extraction (SD) and Soxlet extraction (SE). The oil yields of these methods were compared. And the chemical components were analyzed through GC-MS. It was found that there were distinct differences in the results obtained by three methods.
