To improve the oil yield of Chuanxiong volatile oils and keep their quality same as that of oils prepared by steam distillation (SD) for short), a new technology of coupling water extraction and rectification (WER for short) was applied to isolate Chuanxiong volatile oils. The oil yield, as well as GC-MS chromatogram of the volatile oils extracted by WER and SD were compared. The oil yield of WER (0.50%) was that of SD (0.20%). There were 21 common constituents in the two kinds of volatile oils, which occupied 98.94% of the oils extracted by SD, 98.80% of that by WER, respectively. Moreover, the relative percentage of the common constituents was almost the same. The results indicate that WER could not only increase the oil yield of Ligusticum chuanxiong, but also keep the quality of the oils accord with that extracted by SD.
为提高川芎挥发油的得率并使其质量与水蒸气蒸馏法（简称SD）制备的挥发油相同，采用水提取与精馏耦合新技术（简称WER）提取川芎挥发油。比较了WER法和SD法提取的挥发油的得率以及气相色谱-质谱联用（GC-MS）色谱图。WER法的得率（0.50%）高于SD法（0.20%）。两种挥发油中有21种共有成分，分别占SD法提取挥发油的98.94%、WER法提取挥发油的98.80%。而且，共有成分的相对含量几乎相同。结果表明，WER法不仅能提高川芎挥发油的得率，还能使挥发油质量与SD法提取的挥发油质量一致。
