| Abstract: | Objective] The aim was to filter the best extraction process of Flavonoids from Sambucus williamsii Hance.. Method] Choosing Sambucus williamsii Hance. made in Huaihua as material, the optimum extracting process was selected based on the orthogonal test by supersonic extraction. Result] The optimum condition of supersonic extraction was as follow: Extracting solvents was ethanol at 70%, the ratio of liquid to solid as 30∶1, extracting time was 30 min, extraction power was 420 W. The effect of each condition on the yield was in the following order: Extracting time, extraction power, the ratio of liquid to solid, ethanol concentration. Conclusion] The best optimization outcome had a good repeatability. |
