采用气相色谱法分析茅苍术〔Atractylodes lancea(Thunb.)DC.〕在原产地及引种栽培1年后5个主要挥发油成分的含量变化。结果表明,江苏产茅苍术挥发油成分以苍术酮和苍术素为主;湖北产茅苍术挥发油的主要成分为茅术醇和β-桉叶醇;不同产地野生茅苍术挥发油的主要成分和含量明显不同;引种栽培至同一环境(江苏南京)后,茅苍术挥发油的主要成分及含量差异明显减小,表明产地对茅苍术挥发油有效成分的组成有一定的影响。 

 Contents of five main components of essential oil in rhizome of Atractylodes lancea(Thunb.) DC. which collected from original regions and introduced in the some habit at of Nanjing for one year, were analyzed by GC. The results showed that main components of essential oil from wild A. lancea in Jiangsu Province were atractylon and atractylodin; those from Hubei Province were hinesol and β-eudesmol; there was anobvious difference incontents and components of essential oil between different locations. The variation was decreased clearly after cultivated in Nanjing. It is concluded that production regions give obvious influences on the compositions of active constituents of essential oil in the rhizome.
