Objective: To optimize extraction technology of total flavonoids from Xinjiang Berberis heteropoda fruit. Method: The content of total flavonoids was determined by UV
which was as dependent variable
based on single factor test
with solid-liquid ratio
extraction time and ethanol concentration as independent variables
three factors and three levels Box-Behnken design was adopted
extraction technology conditions of total flavonoids from Xinjiang B. heteropoda fruit were optimized by response surface methodology. Result: Optimal extraction conditions were as followings:extracted 2 h with 33 times the amount of 43% ethanol at 80 ℃
yield of total flavonoids was 24.75 mg·g-1
which accounted for 97.6% of the predicted value(25.37 mg·g-1). Conclusion: Response surface methodology to optimize extraction technology of total flavonoids from Xinjiang B. heteropoda fruit was feasible and reasonable.
