通过气相色谱-质谱联用技术(GC-MS)结合化学计量学方法(CRM),对两种不同品种的桂花挥发油成分进行了定性和定量分析,共鉴定出α-甲基-α-(4-甲基-3-戊烯基)环氧甲醇、β-里哪醇、壬醛、丁香醛、(E)-β-紫罗兰酮、棕榈酸、水杨酸甲酯等71种组分,分别占各自总含量的95.49%、92.28%.结果表明,使用CRM法对重叠峰进行解析,得到纯的色谱和质谱,从而大大提高了分析结果的准确性.

The essential oils from two species of osmanthus fragrans had been analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS) with the help of chemometric resolution method (CRM).71 components accounting for 95.49% and 92.28% of the weight of oil samples were identified,respectively.The constituents included α-methyl-α-[4-methyl-3-pentenyl]oxiranemethanol,β-linalool,nonanal,syringa-aldehyde,(E)-β-ionone,hexadecanoic acid,methyl salicylate,et al.The results showed that the overlapped peak clusters were resolved into pure chromatograms and pure mass spectra by means of the HELP method,with the accuracy of qualitative and quantitative analyses greatly improved.
