Abstract
Objective To optimize the decolorization technology of Oxytropis falcata total flavones with active carbon. Methonds Temperature, stirring time and the content of active carbon were used as the orthogonal experiment factors. The colour of filtrate, the ultraviolet absorption between 260 nm to 420 nm and the content of total flavones were set as the indexes to investigate the optimal decolorization technology. Results The optimal decolorization technology was achieved under the condition as 40 ℃, stirring 5 min with 1% active carbon. Conclusion The decolorization technology is feasible which had good decolorization result and could hold effective ingredient.
