摘要: 气相色谱-质谱法(GC-MS)分析江西大马士革玫瑰精油的化学成分。各色谱峰对应的质谱于NIST标准质谱库中进行相似度检索,共匹配鉴定64个组分,占总峰面积的92.8%;分别提取6个色谱峰的色谱-质谱二维数据,直观推导式演进特征投影分析法(HELP)解析获得新的色谱和质谱。结果结合NIST质谱库检索,与纯品色谱对照,共鉴定出7个组分,总相对含量为49.77%。解析所得组分中,β-苯乙醇、橙花醇、L-香茅醇和香叶醇的相对含量接近ISO 9842:2003《玫瑰油》保加利亚同类油的要求。

Abstract: Gas chromatography-mass spectrometry (GC-MS) was used to analyze the compositions of the essential oil from Jiangxi R. damascene. A total of 64 components accounting for 92.80% of total relative content were identified by similarity searching in NIST mass database. Chromatographic profiles and mass spectra for seven components were resolved from six peak clusters of 2-dimensional multi-component data by using heuristic evolving latent projection (HELP). These components accounting for 49.77% of the total relative content were identified by similarity searches using the NIST, and verified by comparing the retention time with that of pure samples. Relative contents of phenethyl alcohol, nerol, L-citronellol and geraniol were close to requirements of the standard of ISO 9842:2003.

Key words: gas chromatography-mass spectrometry (GC-MS), heuristic evolving latent projection (HELP), essential oil, chemical components
