摘要
分别采用超临界CO2流体提取法、索氏提取法及水蒸气蒸馏法提取桂花中的挥发油,并用GCMS对其化学成分进行分析,采用峰面积归一化法确定各组分相对含量。结果表明,超临界C02流体萃取法提取挥发油共鉴定出64种成分,含量最高组分为棕榈酸;索氏提取法提取挥发油共鉴定出37种成分,含量最高组分为庚烷;水蒸气蒸馏法提取的挥发油共鉴定出29种成分,含量最高组分为γ-葵内酯。3种提取方法所得挥发油组分与含量差异很大,为桂花挥发油进一步开发应用提供了依据。
The essential oil from Osmanthus is extracted by supercritical fluid extraction, soxhlet extraction and steam distillation. The constituents are separated from the essential oil and identified by GC-MS. The relative percentage of the constituents is calculated by area normalization method. The results show that 64 components in the essential oil extracted by supercritical fluid are separated and identified with the highest content of palmitic acid. 37 components are identified by soxhlet extraction with the highest content of heptane. And 29 components are identified by steam distillation with the highest content of gamma-decalactone. The constituents and contents of the essential oil extracted by the three methods exhibit significant differences. These results will provide experimental basis for the further exploitation of the essential oil from Osmanthus.
