Abstract:
Objective To optimize the microwave processing technology of vinegar Corydalis Rhizoma. Methods On the basis of single factor test, the index was evaluated by total rating of content of tetrahydropalmatine, protopine and the total alkaloid, which were determined by HPLC and UV spectrophotometry method, four factors (fire, stuffy time, processing time and dosage of vinegar) were studied by response surface, the microwave processing technology of vinegar Corydalis Rhizoma was optimized by response surface methodology. Results The optimal parameters of microwave processing technology were as follows: microwave power of 70%, stuffy time of 1.5 h, microwave time of 2.6 min, vinegar dosage of 27.5%, the content of tetrahydropalmatine, protopine, and total alkaloid were 0.112 4%, 0.041 8%, and 0.85%. Conclusion Microwave processing can be used as a processing method to enrich the traditional processing technology.
