摘要
研究了超声波辅助提取野生刺五加中总黄酮的最佳工艺条件.通过单因素和正交试验,以总黄酮得率为考察指标,确定出超声波提取刺五加中总黄酮的优化工艺条件为:乙醇体积浓度为60%,液固比为5∶1,超声波时间为20min,超声波功率为500W.将该法与其它提取方法进行了比较,结果表明,超声波法提取刺五加中的总黄酮可提高提取效率,缩短提取时间,减少提取剂用量.
Study on the optimum conditions for flavonoids from wild acanthopanax senticosus with ultrasonic extraction.The yield of flavonoids as criterion, optimization of process conditions with ultrasonic cooperated for flavonoids from it were acquired with single factor and orthogonal test：ethanol concentration 60%,liquid-solid ratio 5∶1,ultrasonic time 20 min,ultrasonic power 500 W.At same time the comparison was conducted between ultrasonic and other extractions,the results showed that the yield of flavonoids from acanthopanax seticosus by ultrasonic extraction was higher than it of the other extractions,ultrasonic extraction was faster and needed less solvent.
