Objective:
To optimize the processing technology of Coptidis Rhizoma and study the effects of different adjuvants on alkaloids during processing.
Methods:
The moistening time of adjuvants (A), processing temperature (B) and processing time (C) were investigated by using the single factor test method and L9 (3(4)) orthogonal experiment design with the contents of four alkaloids as indexes.
Results:
The sequence of importance of the factors that affect the wine processed Coptidis Rhizoma (WC) was C > B > A, turmeric processed Coptidis Rhizoma (TC) and dogwood processed Coptidis Rhizoma (DC) was B > A > C.
Conclusion:
The optimal processing technology of WC, TC and DC are drying for 4 h at 130 degrees C after moistening for 90 min, drying for 3 h at 100 degrees C after moistening for 60 min and drying for 2 h at 160 degrees C after moistening for 90 min, respectively.
