水蒸汽蒸馏和超临界CO2萃取对中药益智挥发油萃取的比较

Extraction of Essential Oil from Alpinia Oxyphylla Miq by Steam Distillation Extraction and Supercritical Fluid CO2 Extraction

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。

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.
