Objective: To optimize processing technology of Coptidis Rhizoma steamed with rice wine. Method: Taking glucose utilization variation rate of insulin resistance(IR) model of 3T3-L1 adipocyte and total contents of active ingredients(columbamine hydrochloride
epiberberine hydrochloride and berberine hydrochloride) as indexes
uniform design test was adopted to optimize processing technology with rice wine consumption
moistening time and steaming time as factors. Result: Coptidis Rhizoma steamed with rice wine could significantly reduce level of glucose in the culture medium.The best processing technology was as follows:rice wine consumption 20%
moistened 2 h and steamed 8 h;Average glucose utilization variation rate was 33.076%
whose relative error was 2.63% with the predicted value of regression model;Average total contents of three kinds of alkaloids was 8.167% with relative error was 1.15% by comparing with the predicted value. Conclusion: Coptidis Rhizoma steamed with rice wine had a role in improvement of IR;This optimized processing technology was stable and feasible.
