| Abstract: | To improve the concentration of flavonoid compounds in the Wahlenbergla marg/nata （Thunb.） A. DC. extraction liquid, influences of ethanol concentration, extraction time and extraction temperature on the absorbance value were analyzed by using the single factor experiment. Orthogonal experimental design was applied to optimize the main factors that affected the concentration of flavonoids in the extract. The results indicated that the optimized factors were 55% of ethanol concentration, 74℃ of extraction temperature and 50 rain of extraction time. |
