铁线莲属植物挥发成分的GC-MS研究被引量:9
2007年
In this paper,essential oils from seven different species of Clematis plant were extracted by water steam distillation.Their chromatography fingerprints were obtained by gas chromatography-mass spectrometry (GC-MS).Compounds were mainly identified through mass spectrometry comparing with the NIST02 database.The overlapped peaks were resolved by chemometric resolution methods,obtaining pure chromatography and pure mass spectrometry.The resolved pure mass spectrometry then compared with NIST02 database.The relative quantitative results were obtained by peak area normalization.62 compounds accounting for 87.96% to 97.19% of the total essential oils were identified.It showed that Eugenol,n-hexadecanoic acid and Z,Z-9,12-octadecadienoic acid were their common main compounds although the contents vary with different samples.The chemical compositions in essential oils from different species or different parts of Clematis are also very different.This research provides us chemical bases for further exploitation of Clematis.
