| Abstract: | Objective To optimize pH value in extraction of Rutin from bud of Sophora japonica L.. Methods] With acid-base Rutin was extracted in different pH of Calcium Hydroxide and Hydrochloric Acid. Results] The yield percentage of Rutin was 18.1% when the pH of base, acid were 9 and 3 respectively. Conclusion] The yield percentage of Rutin is increased with the optimum pH of acid and base. |
