[Abstract] Objective: To optimize the best preparation technology of Astragalus complanatus. Methods:UV-spectrophotometry was applied to determine the total flavonoids content, which was extracted from processed Astragalus complanatus. And the processing was pushed on by L9(34)orthogonal design. Results: The best preparation technology was satisfied with some conditions as follows: its saline concentration 4%, baking temperature 140℃, baking time 4 h ......
