| Abstract: | Objective： To optimize the parameters of the flavonoids from leaves of Ginkgo biloba by orthogonal design. Methods： The extraction technology was optimized by orthogonal experiment with the content of flavonoids which was determined by spectrophotometry, and it was indexes while with ratio of solid to liquid, leaching temperature and pH. Resuits： The optimal extraction technology was as follow： the ratio of solid to liquid was 1：15, leaching temperature was 70℃ and pH was 8. Conclusion： This extraction technology is stable, reasonable and feasible, and it is applicable for experimental studies. |
