摘要
本文主要研究了传统中药广东益智的挥发油化提取工艺。比较了水蒸汽蒸馏(SDE)和超临界CO2萃取技术(SFE-CO2)对益智的挥发油的提取率,并运用GC-MS法分析了两种提取物中的挥发油化学成分。结果表明,两种方法获得的益智挥发油的主要成分组成基本一致。
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.
