密蒙花挥发油化学成分的研究

目的]对密蒙花（Buddleia offiinalis Maxim）挥发油化学成分进行研究,为密蒙花的进一步开发利用提供科学依据。方法]采用水蒸气蒸馏法从密蒙花中提取挥发油,用气相色谱-质谱法对其化学成分进行分析,以归一化法计算各个化学成分的相对含量。结果]共分离出46个峰,鉴定了其中27个化学成分,占挥发油总量的72.41%。结论]密蒙花挥发油中的主要成分为棕榈酸（14.07%）、6,10,14-三甲基-2-十五烷酮（12.92%）、二十一烷（6.15%）、二十七烷（3.28%）。

Study on Dhemical Constituents of Essential Oil in Buddleia officinalis Maxim

Objective] The aim was to study the chemical constituents of essential oil in Buddleia officinalis Maxim and provide the scientific basis for further exploitation and utilization. Method] 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. Result] 46 peaks were separated and 27 constituents were identified,which were composed of about 7...
