Typhonii Rhizoma is a toxic traditional Chinese medicine. Its toxic components remained unclear. To compare chemical composition of volatile oils from fresh and processed Typhonii Rhizoma qualitatively, volatile oils were obtained by stream distillation and analyzed by GC-MS. The data obtained from GC-MS were processed by principal component analysis. From the essential oils of fresh and processed Typhonii Rhizoma, 43 compounds and 34 compounds were identified respectively. The chemical composition and content in the two oils was different. In the two essential oils 15 identical components were detected. The chemical components and their contents in the essential oils are changing with the storage.
白附子是一种有毒的中药。其有毒成分尚不清楚。为了定性比较鲜品和炮制品白附子挥发油的化学成分，采用水蒸气蒸馏法提取挥发油并进行气相色谱-质谱联用（GC-MS）分析。将GC-MS获得的数据进行主成分分析。从鲜品和炮制品白附子的挥发油中分别鉴定出43种和34种化合物。两种挥发油的化学成分和含量不同。在两种挥发油中检测到15种相同成分。挥发油中的化学成分及其含量随储存时间而变化。
