Abstract
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%.
