Objective:To study the constituent changes of Polygonati Rhizoma before and after processing. Method: Polygonati Rhizoma was prepared with wine by stewing for different time. Headspace injection-GC-MS was used and the structures of compounds were identified by Data Base Retrieval and compared with the retention indexes of n-alkanes standards. The relative content of every constituent was obtained from the peak area normalization method of chromatographic peaks. Result: There are 12 common compounds between raw products and processed products
yet the relative content was different. Compared with raw products
20 compounds produced and 7 disappeared after different processed for different time. Conclusion: The chemical constituents and content have changed in the root of Polygonati Rhizoma before and after processing.
