| 摘 要： | 利用水蒸气蒸馏法提取沙枣花挥发油，采用气相色谱-质谱(gas chromatography-mass spectrometry，GC-MS)联用技术对其化学成分进行分离和鉴定，并用峰面积归一化法确定各组分的相对含量。结果共分离出64个组分，鉴定出其中54个化合物，占总质量分数的96.89%；其主要成分为反式肉桂酸乙酯(77.36%)、(E)-4-丙烯基-2-甲氧基苯酚(3.03%)、乙缩醛(2.70%)、顺肉桂酸乙酯(1.09%)、苯乙酸乙酯(1.06%)、苯甲酸乙酯(1.03%)、反式橙花叔醇(1.03%)。

| Abstract: | Steam distillation extraction followed by GC-MS was used to analyze the chemical composition of volatile oil from the flowers of Elaeagnus angustifolia L.Peak area normalization method was used for quantification.Totally 64 compounds were separated,of which 54 were identified and accounted for 96.89% of the total volatile oil,mostly including ethyl trans-cinnamate(77.36%),(E)-2-methoxy-4-(1-propenyl) phenol(3.03%),acetal(2.70%),ethyl cis-cinnamate(1.09%),ethyl benzenacetate(1.06%),ethyl benzoate(1.03%) and ... |
