OBJECTIVE: To establish initial processing technology of Corydalis yanhusuo.METHODS: Investigated the effect of the factors such as slice method, dry method, drying temperature on the content of water-extract, ethanol-extract, effective component in Corydalis yanhusuo pieces. Compared the quality with that of the traditional initial processing samples.RESULTS: The best initial process method was: cut fresh Corydalis yanhusuo into 4 - 5 mm thick slices, dry at 70 - 80 degrees C or microwave dry.CONCLUSION: The study provides theoretical base for modifying the initial processing.
