Objective: To investigate the chemical variation and its mechanism in processing of Cibotium barometz.
Method: The methods of TLC and HPLC were carried out to identify the chemical variation in processing of C. barometz, and the compounds changed significantly were isolated by chromatography.
Result: Chemical components were changed significantly in processing of C. barometz.
Conclusion: Maillard reaction is involved in the process of rhizome C. barometz, which may be contributed to the activity between raw and processed C. barometz.
