气相色谱-质谱联用分析白兰叶油成分

Study on Chemical Constituents of Essential Oil of Michelia Leaves by Gas Chromatography Mass Spectrometry

采用气相色谱－质谱联用技术对苏州产白兰叶油的化学成分进行了分析，分离出３３个峰。鉴定了其中２７种成分，占总峰面积的９７％，并对油中的主要化学成分芳樟醇用气相色谱－傅立叶红外光谱法进行了验证。

The essential oil in Michelia leaves was extracted by steam distillation. The oil obtained was dried with anhydrous magnesium sulfate. The chemical constituents were analyzed by GC MS. Thirty three peaks were separated by GC, and 27 of them were identified by MS with NBS mass spectral data and Wiley/NBS registry of mass spectral data. The structure of linalool was further verified by GC/FTIR. The identified constituents represent 97% of the peak area of the essential oil on FID. The major chemical constituent of them are linalool, trans caryophyllene and diethyl o phthalate.
