| 摘要: |
| [目的]研究丙酮/(NH4)2SO4双水相萃取体系对分离槐米中芦丁的影响因素。[方法]利用正交设计法进行优化,并把28.57%的硫酸铵溶液与等体积的70%的丙酮混合溶液,调至pH=9形成的双水相,两相的体积比(V上/V下)是1.62。[结果]萃取体系的上相中芦丁含量达到95.92%。[结论]丙酮/(NH4)2SO4双水相萃取体系分离芦丁具有良好的选择性。 |

| Abstract: |
| [Objective] Study on the influence factors of Rutin Extraction from Flos Sophorae Immaturus by acetone-ammonium sulfate aqueous two-phase system.[Methods] The technique conditions was optimized by orthogond test.The aqueous two-phase system (pH 9.0) consisted of aqueous (NH4)2SO4 solution (28.57%,W%) and acetone (70%,W%) in equal volume,and ratio of volume of two phases (Vl/Vh,Vl is light phase,Vh is heavy phase) is 1.62.[Results] By this extract system,the content of rutin in light phase is 95.92%.[Conclusion] This result revealed that the aqueous liquid two-phase system was effective for separating rutin. |
