Abstract:
Objective:To optimize the ultrasound-assisted extraction process of total flavonoids in Vaccinium bracteatum Thunb. leaves. Methods:The single factor test and orthogonal test were adopted with the content of total flavonoids as the index, and the ultra-sound-assisted extraction was optimized with the concentration of solvent, extracting time, ratio of raw material to liquid and extraction times as the factors. Results:The optimal extraction conditions were 70% ethanol with 40-fold volume, extracting 2 times with 30 mi-nutes per time. Conclusion:The extraction process is stable and feasible, and all the results are useful references for the extraction process improvement.
