本文报道了毛细管气相色谱—质谱法分析中药千年健挥发油的化学成分,鉴定了34个组分,其中29个化合物在该植物中被首次发现。并对水蒸汽蒸馏提取挥发油的方法与中草药粉末直接进样的闪蒸分析方法作了比较,两种方法获得的结果基本一致。
In this paper, the chemical constituents of the essential oil of Chinense Millet were analyzed by capillary gas chromatography-mass spectrometry (GC-MS), and 34 compounds were identified. Among them, 29 compounds were found for the first time in this plant. The methods of extracting volatile oil from steam distillation were compared with the flash analysis method of direct injection of Chinese herbal powder. The results obtained by the two methods were basically the same.
