A solid phase microextraction sampling method using pencil-lead fibre coupled with gas chromatography-mass spectrometry was used to monitor the organic volatile compounds of the roots, leaves and gum of Astragalus compactus. Under optimised conditions, a range of volatile compounds were recognised in different parts of A. compactus. Based on the results obtained, the nature and level of the volatiles vary in distinct parts of the plant. In comparison with other Astragalus species investigated, only one volatile organochlorine compound, tetradecane,1-chloro, was identified in roots. Intriguingly, the toxic chlorinated component was not detectable in the gum samples. These findings highlight the higher quality of the gum of A. compactus compared to the gums of some other Astragalus species, which are reported to be contaminated with chlorinated components.
采用铅笔芯纤维固相微萃取采样法结合气相色谱-质谱联用技术，监测了蒙古黄芪根、叶和胶中的有机挥发性化合物。在优化条件下，在蒙古黄芪的不同部位识别出了一系列挥发性化合物。根据所得结果，植物不同部位的挥发性物质的性质和水平不同。与其他研究的黄芪属物种相比，仅在根中鉴定出一种挥发性有机氯化合物，十四烷，1-氯。有趣的是，胶样品中未检测到有毒的氯化成分。这些发现表明，蒙古黄芪胶的质量高于一些其他黄芪属物种的胶，据报道，这些胶种受到氯化成分的污染。
