MAHD法与HD法分离调味香料挥发油的比较研究

Comparison of Microwave- Assisted Hydrodistillation with the Traditional Hydrodistillation in the Separation of Volatile Oil Existed in Natural Spice

微波辅助水蒸气蒸馏(MAHD)是一项新的蒸馏提取技术。利用该项技术提取调味香料清化桂的挥发油,并利用GC—MS技术测定了所分离挥发油的化学成分。与传统水蒸气蒸馏法(HD)比较发现,MAHD节省时间,挥发油中高沸点的含氧化合物组分含量高于HD,挥发油经济价值较高。

Microwave-assisted hydrodistillation （MAHD） is a new extraction technique for hydrodistillation （HD） . In the present study, the technique was used to extract the volatile oil of natural spice, Cinnamomum loureiroi. The chemical composition of the oil was identified using GC/MS technique. Comparison with traditional HD, it was found that MAHD save time and the obtained oxygen-containing compounds were more than those by HD. Therefore, the MAHD volatile oil has more economic value than HD oil.
