摘要
研究广西甜茶中总黄酮的超声提取工艺,通过正交试验得出最佳提取条件为:乙醇浓度30%,料液比1∶30,提取温度50℃,提取时间40min。在该条件下总黄酮的提取得率为3.85%。
The extraction technique of total flavonoids from Rubus Suavissimus S. Lee with Ultrasonic was discussed, and the optimum conditions were determined with orthogonal experiments. They avere.. 30 % ethanol as extracting solvent; extraction temperature was 50 ℃ ; extraction time was 60 min and the ratio of material to liquor was 1 ： 30. under the optimal conditions, the yield of total flavonoids was 3.85%.
