Study on the Orthogonal Test of Concocted Processing Integration in Fresh Corydalis Rhizoma

OBJECTIVE To study the technologies of concocted processing integration in fresh Corydalis Rhizoma. METHODS The orthogonal test of three factors at three different levels was used. The effective constituents content was determined contrast with the traditional processing. RESULTS The two methods of 4 mm slice, 4.6% acetic acid, vacuum pumping for twice and 4 mm slice, about 30% water content after drying, soaking in rice vinegar were optimal process, and can improve the concentration of etrahydropalmatine and achieve the effect of processing. CONCLUSION The study provides the feasibility of concocting processing integration in fresh Corydalis Rhizoma.
