索尔邦百合花挥发油不同提取方法的GC-MS比较

The Comparision of Volatile Oils in Lilium Sorbonne by Different Extraction Methods with GC-MS

采用气液相连续萃取法和水蒸气蒸馏法对索尔邦百合花的挥发油进行提取，气相色谱-质谱法（Gc—Ms）结合谱图库检索分离并鉴定了其化学成分，并用峰面积归一化法测定了各成分的百分含量。结果表明：两种方法共分离出95个组分，确定了其中89种化合物。其主要成分为烯、醇、酯、醛、酸和烷类化合物。与水蒸气蒸馏法相比，气液相连续萃取法多革取出29种化合物，增加的化合物中相对分子质量小、沸点低的组分较多。另外，两种方法共有的低沸点化合物中，气液相连续革取法革取出的化合物含量均较高。

The volatile Oils was extracted by steam distillation method and gas liquid phase continual extraction method from lilium Sorbonne, and was analyzed by gas chromatography mass spectrometry（GC-MS） and spectral library. Finally the area normalization was used to measure the relative percentages of each of the components. The results showed that 95 components were separated and 89 components were identified.The main components are alkene, alcohol, ester, aromatic compounds, aldehyde and alkane series. Comparing with steam distillation method, more than 29 components with lower boiling points and small relative molecular mass were extracted by gas liquid phase continual extraction method. The relative percentage is higher of lower boiling points components extracted by gas liquid phase continual extraction method.
