| 摘 要： | 采用无溶剂微波辅助提取与微波水蒸气蒸馏法提取薄荷叶和花椒挥发油,气相色谱-质谱(GC-MS)分析挥发油化学成分,与传统的水蒸气蒸馏对比,考察了微波对挥发油化学成分的影响.结果表明,微波促使薄荷叶挥发油中的薄荷醇氧化,转变为长叶薄荷酮和少量的薄荷呋喃酮.花椒挥发油中的按油素等化合物受质子的催化,在长时间温度较高的提取条件...

| Abstract: | Essential oil from mentha hapioealyx briq and zanthoxylum bungeanum maxim was extracted by solvent free microwave extraction(SFME) and microwave assisted hydro-distillation(MAHD),and GC/MS was used for the qualitation and quantification analysis for the chemical composition in the essential oils.Hydrodistillation(HD) was compared to study the contribution of microwave to the composition changes in the extraction process.The experimental results showed that microwave can promote the menthol from the essentia... |
