OBJECTIVE To establish integration processing method for pretreating and vinegar producing Corydalis yanhusuo. METHOD Different processing methods were contrasted with the traditional processing technology, and contents of corydalis B, water extract and ethanol extract in samples of different processing products were determined. RESULT The content of corydalis B were best in the samples of vacuumizing C. yanhusuo chips scaked in rice vinegar for twice or soaked in rice vinegar after chip drying. The water extract was highest in the samples of chip soaked in rice vinegar after drying, followed with chip vacuumizing twice, and there were no remarkable difference between the other samples and the traditional process. The difference of ethanol extract was not remarkable in all the samples. CONCLUSION The study provide the feasibility of C. yanhusuo producing and concocting integration processing.
