摘要: 目的 优选镰形棘豆总黄酮活性炭脱色工艺。 方法 以温度、时间和活性炭用量为考察因素,脱色液颜色、260~420 nm紫外吸收情况和总黄酮含量为考察指标,采用正交试验法探究最佳脱色条件。 结果 脱色最佳工艺为在40 ℃下,加入1 %活性炭,搅拌5 min。 结论 该脱色工艺可行,既能达到脱色效果,又能保留有效成分。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.
