摘　　要：目的对8种化湿药挥发油成分进行定性、定量分析，并比较挥发性成分的异同。方法在运用气相色谱-质谱（GC／MS）技术的基础上采用HELP（直观推导式演进特征投影法）对产生的二维色谱-质谱数据进行解析，对组分进行定性和相对定量分析。结果鉴定出相对共有成分达60余种，8种药材挥发性成分中均含有桉叶油醇（Eucalyptol，0．01％～82．41％）和环氧石竹烯（Caryophyllene oxide，0．02％～5．5％）。结论8种化湿药挥发油共有成分大多数为萜类化合物及其衍生物，但其含量存在较大差异。Objective To detect chemical components of the volatile oil in eight samples of damp dispersing herbs. Methods Gas chromatography - mass spectrometry （ GC - MS） with heuristic latent projections （HELP） method, and overall volume integration method were used. Results More than 60 relatively common components were identified. Eucalyptol （ relative content tr - 82. 41% ） and Caryophyllene oxide（0.02% -5.5% ） are the common main compounds of the eight plants. Conclusion There is a lot differences in the chemical compounds among the eight damp dispersing herbs, Terpenes and their derivatives are the main components, and also in percentages on many levels.
