长白鱼鳞云杉挥发性成分的气相色谱 - 质谱分析

采用水蒸气蒸馏法提取长白鱼鳞云杉中的挥发性成分,利用气相色谱 - 质谱联用(Gas chromatography - mass spectrometry, GC - MS)技术对提取的挥发性成分进行了分离和检测,并用峰面积归一化法计算了各成分的相对百分含量.实验结果显示:长白鱼鳞云杉挥发性成分的提取率为0.86%,在检测出的76个峰中共鉴定出butyl - 2 - ethylhexyl phthalate(相对百分含量为25.32%)、油酸(相对百分含量为14.28%)、十六酸(相对百分含量为10.44%

Analysis of volatile components of Picea jezoensis var.komarovii by gas chromatography-mass spectrometry

In this work, the volatile components in Picea jezoensis var.komarovii were obtained by steam distillation.The volatile components were separated and detected by gas chromatography - mass spectrometry(GC - MS), the relative percentage composition of each component was calculated by peak area normalization method. The results showed that the extraction rate of volatile compounds in Picea jezoensis var.komarovii was 0.86%, 76 peaks were detected by GC - MS and 43 of them were identified.The content from high to low is butyl - 2- ethylhexyl phthalate(relative percentage 25.32%), oleic acid(relative percentage 14.28%), hexadecenoic acid(relative percentage 10.44%), 4 - octadecylmorpholine(relative percentage 7.67%), octadecyl dimethyl tertiary amine(relative percentage 5.87%), stearic acid(relative percentage 5.67%), 8 - hexadecane(relative percentage 5.17%), L - bornyl acetate(relative percentage 3.04%)and other components.These components are mainly aliphatic compounds, while the volatile components of Picea jezoensis are mainly terpene compounds.The results can provide a reference for the development and utilization of Picea jezoensis var.komarovii.
