采用水蒸气蒸馏法从独活中提取挥发油。采用不同类型的毛细管柱进行分析 ,找出最佳分析条件 ,共分离出50个峰 ,用归一化法测定其相对含量 ,并用气相色谱 -质谱法对化学成分进行鉴定 ,共鉴定了40个成分 ,占挥发油总成分的80 %以上。 Volatile oil is extracted from solstice by steam distillation. Different types of capillary columns were used for the analysis, the best analytical conditions were found, 50 peaks were separated, the relative content was determined by normalization method, and the chemical constituents were identified by gas chromatography-mass spectrometry. A total of 40 Ingredients, accounting for more than 80% of the total volatile oil components.
