摘　　要：为了分析荷花中挥发油的化学成分,采用水蒸气蒸馏法从新鲜荷花中提取挥发油,用气相色谱-质谱联用技术(GC-MS)对挥发油的化学成分进行分离分析,并应用峰面积归一化法测定各成分的含量。试验共分离出95个峰,鉴定出80种化合物,其中主要成分为乙酸乙酯(6.61%)、1,4-二甲氧基苯(9.06%)、肉桂醛(6.60%)、肉桂醇(10.20%)、茉莉酮(4.75%)等挥发性的醇类、脂类、醛类、酸类和烯类化合物。通过试验可知,GC-MS能很好地鉴定出荷花挥发油的化合物组成,为荷花资源的开发利用奠定基础。In order to analyze the chemical constituents of volatile oil in lotus flower, this paper used the method of steam distillation to extract volatile oil from fresh lotus flower.The chemical constituents of volatile oil were separated and analyzed by gas chromatography-mass spectrometry (GC-MS), and the percentage content of each component was determined by peak area normalization method.A total of 95 peaks were isolated and 80 compounds were identified, including acetic ether (6.61%), 1,4-dimethoxy benzene (9.06%), Cinnamic aldehyde (6.60%), Cinnamic alcohol (10.20%), Jasmone (4.75%) and other volatile alcohols, lipids, aldehydes, acids and olefins.The results showed that GC-MS can determine the composition of volatile oil of lotus well and lay a foundation for the development and utilization of lotus resources.
