摘要
目的:分析天仙子中挥发油成分组成,比较炮制对其挥发油组成的影响。方法:GC-MS方法分析天仙子中挥发油组成,用气相色谱面积归一化法测定了各成分的相对百分含量。结果:经毛细管色谱分离并鉴定出29个峰。其中含量最高的是棕榈酸(28.30%)、其余依次为亚油酸(26.85%)、油酸(14.39%)、己醛(10.24%)、硬脂酸(1.81%)等。首次采用GC对不同炮制品中挥发油成分进行了比较分析。结论:与生品比较,清炒品中多数成分含量均下降,醋制品中多数成分含量大幅度增加,未见成分组成的质变。
Objective： To analyze the compositions of volatile oil in the seeds of Hyoscyamus niger L.;and to investigate the influence on processing the compositions of volatile oil in the seeds.Methods： GC-MS was used to analyze the compositions of the volatile oil in the seeds.Results： 29 compositions were isolated and identified,including palmitic acid（28.30%）,linoleic acid（26.85%）,oleic acid（14.39%）,hexanal（10.24%）,and stearic acid（1.81%） etc.The volatile oil in the processed samples was first analyzed by GC-MS.Conclusion： Comparing with the raw samples,the relative content of most compositions in the stir-fried samples was decreased and most compositions in the vinegar processed were increased.
