茸毛木蓝挥发性成分的全自动热脱附-气相色谱-质谱分析

Volatile Constituents from Indigofera stachyodes Lindl. by automatic thermal desorption-gas chromatography-mass spectrometric

  • 摘要: 为了进一步开发茸毛木蓝的药用价值,研究采用全自动热脱附-气相色谱-质谱(automatic thermal desorption-gas chromatography-mass spectrometric,ATD-GC-MS)联用技术,对用动态顶空密闭循环吸附法捕集到的茸毛木蓝花朵以及新鲜根的挥发性成分进行分析检测,并运用峰面积归一化法计算出其相对含量.结果显示:从茸毛木蓝花朵挥发物中检测出7种化合物,主要是烷烃、烯烃、醛、醇类,其中烷烃含量最高(72.16%),其次是烯烃(15.59%),醛(8.88%),醇(3.3%);从茸毛木蓝根的挥发物中检测出13种化合物,主要是醇、烯烃、酯和烷烃类等化合物,其中醇类含量最高(32.96%),烯烃(31.78%),酯类(14.79%),烷烃(9.36%).并推断出醛类和萜烯类化合物是茸毛木蓝花朵和根的主要香气成分.

     

    Abstract: In order to further develop the medicinal value of Indigofera stachyodes Lindl.,an automatic thermal desorption-gas chromatography-mass spectrometric (ATD-GC-MS) system was applied to analyze the volatile composition of the flowers and fresh root of Indigofera stachyodes Lindl. based on dynamic head-space closed cyclic adsorption sampling.The quantification of volatile compounds was carried out using area normalization method.Seven contents of identified volatile compounds in the fresh flowers were identified,mainly alkane,alkene,aldehydes,and alcohols,and among them,alkane were the most predominant group of compounds,with a relative content of 72.16%,followed by alkene(15.59%),aldehydes(8.88%),and alcohols(3.3%);Thirteen contents of identified volatile compounds in the root were identified,mainly alcohols,alkene,ester and alkane.Alcohols were the most predominant group of compounds(32.96%),followed by alkene(31.78%),ester(14.79%)and alkane(9.36%).Overall,the special aroma ingredients of Indigofera stachyodes Lindl. are aldehydes and terpenes.
