Abstract: Objective: To optimize the extraction of total flavonoids from the flowers of Rosa xanthina Lindle. Methods: An L9 (34) orthogonal array design was employed to optimize the extraction conditions. The effects of ethanol concentration, solid-to-liquid ratio, extraction time and temperature were studied on extraction rate of total flavonoids, as determined by ultraviolet (UV) spectrometry. Results: The optimal extraction conditions were 75% ethanol concentration as solvent solid-to-liquid ratio of 1:30 and 75 ℃ for an extraction duration of 1 h. Under the optimal extraction conditions, the maximum extraction rate was up to 32.77 mg/g. Conclusion: The optimal extraction process obtained in this study has excellent stability.
