| titleOfInvention | Method for purifying taxifolin by utilizing high-speed countercurrent chromatography (HSCCC) |
| abstract | The invention relates to a method for purifying taxifolin by utilizing high-speed countercurrent chromatography (HSCCC). The method comprises the following processing steps: a. grinding dry taxifolin, adding water to decoct ground taxifolin, adding activated carbon to decolor the filtrate, and filtering the filtrate while the filtrate is hot; b. concentrating the filtrate at reduced pressure, drying and crystallizing the concentrate, and recrystallizing the crystal substances with acetic acid; c. separating the crystal substances by using HSCCC, and collecting the target ingredients according to a high performance liquid chromatography-evaporative light-scattering detector (HPLC-ELSD) detection pattern. The method is simple in process, little in pollution and high in product purity and is suitable for industrial production. |
