【摘要】 采取闪蒸气相毛细管色谱法和气相毛细管色谱—质谱法研究了宁夏六盘山区产川芎的挥发油化学成分,色谱分离出50多个峰,质谱鉴定了24个成分,主要是川芎酜内酯(46.37％)、丁基酞内酯(13.87％)、新蛇床内酯(6.98％)和丁烯基酜酯(4.8％)。红外光谱图中有较强的内酯特征吸收峰,为质谱所鉴定的以上主要成分提供了佐证。将闪蒸气相色谱法与蒸气蒸馏提取气相色谱法进行对照,二者的色谱图基本相符,前者是分析天然产物挥发性成分更加简便、迅速的微量方法。更多还原

【Abstract】 Chemical Constituents of Volatile oil of Ligusticum chuanxiong Hort collected from the Monte HexaPan regions of Ningxia, were studied by means of capillary gas chromatography-mass spectrometry, accompanied by flash vaporization GC.Above 50 ingredients were separated, of which 24 components were identified, the first major constituent being senkyunolidc (46.37％), and the second and third major components butylphthalide (13.87％) and neocnidilide (6.98％) respectively. These compounds have not been isolated from the volatile oil of this herb species previously. The method of flash-vaporization GC was compared with that of steam-distillation extraction GC, results of these two were consistent,and the former possesses the advantages of high speed, simple manipulation, micro-quantity of required herb sample, and exclusion of the interference of the extracting solvents, proved to be an exquisite method for analyzing volatile constituents of medicinal herbs.更多还原
