【摘要】 目的对云南大理产水芹挥发油进行化学成分的研究,为水芹的进一步开发和利用提供科学依据。方法采用水蒸气蒸馏法从水芹中提取挥发油,用气相色谱-质谱法对化学成分进行分析,以归一化法计算各个化学成分的相对含量。结果共分离出61个峰,鉴定了其中16个化学成分,占挥发油总量的96.46%。结论水芹挥发油中的主要成分为苯氧乙酸烯丙酯(80.17%)、桉叶-4(14),11-二烯(6.83%)、2,3-二氢-3-甲基-3-苯并呋喃甲醇(2.94%)、柠檬烯(1.63%),云南大理产水芹挥发油中萜类化合物及其衍生物含量在13%以上,苯氧乙酸烯丙酯含量高,可用作食品工业和化妆品工业的香料。更多还原

【Abstract】 Objective To study the chemical constituents of the essential oil in Oenanthe javanica(BL.) DC,and provide the scientific basis for exploitation.Methods The essential oil was extracted by steam distillation.The chemical constituents of the essential oil were analyzed by GC-MS.The relative contents of these constituents were calculated using square peaks to normalization.Results 61 peaks were separated and 16 constituents were identified,which were composed of about 96.46% of the total essential oil.Conclusion The main constituents are allyl phenoxyacetate(80.17%),eudesma-4(14),11-diene(6.83%),2,3-dihydro-3-methyl-3-benzofuran-methanol(2.94%),limonene(1.63%).The essential oil in Oenanthe javanica(BL.) DC from Dali,Yunnan can be used in the food service industry and the cosmetic industry as spices.更多还原
