| Objective To optimize the extraction process of total flavonoids from the branchesof Vernonia cumingiana Benth.Methods Single factor experiment method was used to study the effects of ultrasonic power, extraction temperature, ethanol concentration, liquid-to-material ratio and extraction time on the extraction rate of total flavonoids from Vernonia branches and verified by orthogonal experiments.Results The ultrasonic power was 540W, the extraction temperature was 70℃, the ethanol concentration was 70%, the ratio of material to liquid was 1:20, and the extraction time was 70min, which were the best extraction conditions.Under these conditions, the content of total flavonoids in the venomous root Vernonia branch was 81.59 mg·g-1Conclusion In this study, the extraction process of the total flavonoids from the branches of Vernonia vulgaris was optimized.The process is stable and feasible, with good reproducibility and high extraction efficiency. |
