摘要/Abstract

摘要： 应用气相色谱法(GC)对100株茅山苍术根茎鲜质量和挥发油4个组分苍术素、苍术酮、苍术醇、β-桉叶醇含量进行了测定,并分析了4种挥发油组分之间及其与鲜质量的相关性.结果表明:野生生境下,茅山苍术根茎质量变异幅度较大,但质量普遍偏小,仅7%单株根茎质量超过30g;茅山苍术全部单株含苍术素且变异度最小,3%单株不含β-桉叶醇、7%单株不含苍术酮和50%单株不含茅术醇;野生茅山苍术根茎中挥发油组分以苍术素为典型成分,含量较高,茅术醇的有无可以作为茅山苍术与其他地区苍术区分的一个依据.茅山苍术根茎鲜质量仅与苍术酮组分呈显著正相关,苍术素和苍术酮之间的相关系数最高,茅术醇和β-桉叶醇之间的相关系数也较高,解释了茅苍术中茅山苍术和其他地区的茅苍术挥发油组分中苍术素和苍术酮及茅术醇和β-桉叶醇是协同变化的原因.

Abstract: One hundred individuals of rhizomes of Atractylodes lancea(Thunb.)DC were collected from Mt. Maoshan and 4 essential oil components (atractylodin, atractylon, hinesol and β-eudesmol) were determined by GC. The correlations among the 4 essential oil components and between the rhizome mass were analyzed. Results showed that, under wild conditions, variation among masses of rhizomes, was large, but their masses were small generally, with only 7% individuals of rhizomes having mass more than 30 g. All rhizomes of A. lancea from Mt. Maoshan contained atractylodin which had the least variation, whereas, β-eudesmol was absent in 3% individuals of rhizomes, atractylon was absent in 7% of individuals and hinesol was absent in 50% of individuals. Atractylodin was the typical essential oil component in the rhizomes of wild A. lancea with high content. The rhizomes collected from Mt. Maoshan and other areas could be distinguished by the absence or presence of hinesol. The mass of rhizomes was positively correlated with atractylon. The correlation between atractylodin and atractylon was the highest,and the correlation between hinesol and β-eudesmol was also high, which explained the coordinated changes between atractylodin and atractylon, as well as between hinesol and β-eudesmol.

Key words: Atractylodes lancea(Thunb) DC. from Mt. Maoshan, essential oil components, correlation
