石菖蒲-远志药对配对前后水煎液中挥发性成分的含量变化分析

Analysis of volatilis components' variation in decoction before and after Acorus Tatarinowii Schott and Polygala tenuifolia Willd matched-pairs

目的研究经典药对石菖蒲-远志配伍前后水煎液中挥发性成分的含量变化。方法煎煮法分别获得石菖蒲-远志药对和单味药材的水煎液,气相色谱法(GC)测定水煎液中α-细辛醚和β-细辛醚的含量。结果石菖蒲-远志药对中α-细辛醚的含量为0.048%,β-细辛醚的含量为0.812%;石菖蒲单煎中α-细辛醚的含量为0.049%,β-细辛醚的含量1.012%;结论石菖蒲、远志配伍后,α-细辛醚含量无明显变化,β细辛醚含量显著降低(P<0.05)。

Objective To research the volatilis components’ variation in decoction before and after Acorus Tatarinowii Schott and Polygala tenuifolia Willd matched- pairs. Methods The decoction of matched pair of Acorus Tatarinowii Schott and Polygala tenuifolia Willd and each herb were extracted by bulliens aqua,the contents of α- asaricin and β- asaricin in the decoction were determined by GC. Results The contents of α- asaricin and β- asaricin in the decoction of matched pair of Acorus Tatarinowii Schott and Polygala tenuifolia Willd were 0. 048% and 0. 812%. The contents of α- asaricin andβ- asaricin in the decoction of Acorus Tatarinowii Schott were 0. 049% and 1. 012%. Conclusion After the match of Acorus Tatarinowii Schott and Polygala tenuifolia Willd,the content of β- asaricin was decreased obviously（ P 〈 0. 05）,but there was not obviously change of α- asaricin.
