摘要
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 chromatographymass 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%)、4十八烷基吗啉(相对百分含量为7.67%)、十八烷基二甲基叔胺(相对百分含量为5.87%)、硬脂酸(相对百分含量为5.67%)、8十六烷烯(相对百分含量为5.17%)和左旋乙酸冰片酯(相对百分含量为3.04%)等43个成分,且这些成分主要为脂肪族类化合物,而同属植物鱼鳞云杉的挥发性成分主要为烯萜类化合物.该结果可为长白鱼鳞云杉的开发利用提供参考.
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.
