Abstract:
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.
