七里香蔷薇花属蔷薇科蔷薇属,学名Rosa banksia R.Br.normalis Regel。它大量地野生在我国秦岭山区。我们采用了甘肃省成县地区的七里香浸膏~*。将它用乙醇在0℃时脱蜡三次,脱蜡后的净油用硅胶柱层析,并将其粗分成萜烯和含氧部分两段。取其含氧部分用气相色谱-质谱联用仪进行分析鉴定。重建总离子流(RIC)色谱图上有64个主峰(见图1、2)。把这些谱图对31,000个化合物的EPA/NIH/MSDC谱库进行检索并对照了其它已发表的谱图(EPA/NIH Mass SpectralData Base;Mass Spectrometry Data Centre,Eight Peak Index of Mass Spectra等),鉴定出15个化合物,它们是:丁香酚,甲基丁香酚,γ-紫罗兰酮,二氢β-紫罗兰酮,α-紫罗兰
Qili incense Rosaceae Rosaceae Rosa genus Rosa banksia R.Br.normalis Regel. It is wildly abundant in China’s Qinling Mountains. We have adopted the Qilixiang extract of Cheng County, Gansu Province. This was dewaxed three times with ethanol at 0 ° C, and the dewaxed absolute oil was subjected to silica gel column chromatography and roughly divided into two sections of terpene and oxygen-containing fraction. Take its oxygen content by gas chromatography - mass spectrometry analysis identified. There are 64 main peaks in the reconstructed total ion current (RIC) chromatogram (see Figure 1, 2). These spectra were searched for EPA / NIH / MSDC libraries of 31,000 compounds and compared to other published spectra (EPA / NIH Mass Spectral Data Base; Mass Spectrometry Data Center, Eight Peak Index of Mass Spectra, etc.), identified Out of 15 compounds, they are: eugenol, methyl eugenol, gamma-ionone, dihydro-beta-ionone, alpha-violet
