Abstract:
The extraction conditions of total flavonoids from Salicornia bigelovii Torr.were optimized.Effects of ethanol concentration,microwave power,solid-liquid ratio,extraction time and pH value on the extraction of total flavonoids’were studied by single-factor experiments.Based on the single-factor test,the optimal extraction conditions of total flavonoids from Salicornia bigelovii Torr.were obtained through the response surface methodology.The results showed that the optimum extraction conditions of total flavonoids from the Salicornia bigelovii Torr.were adding 80 times amount 85% ethanol and extracting for 14 minutes at 70 ℃ and pH 10.5,the extraction rate of total flavonoids was 6.89% under the optimal extraction conditions.This result was basically consistent with the predictive value(i.e.6.81%)of the fitted equation.
