| Abstract: | Objective： To optimize the technology of alcohol precipitation techniques for the optimal compound of Cortex Fraxini. Method： The method is orthogonal experiment design. Doxycycline content is determined by UV spectrophotometry. Solution concentration, alcohol concentration, at the time for the impact of factors and table L9（34） is used to do orthogonal design experiment. Results： Selection process for the liquid increases the concentration （1.1 to 1.2）, alcohol concentration （60 percent）, at the time （24 h）. Conclusion ： The contents of Aesculetin obtained are higher by the optimum technology |
