摘　　要：利用均匀设计法优化了超声波提取白桦树皮中鞣质的工艺，确定了最佳工艺条件。超声波辅助提取桦树鞣质的最佳条件为：乙醇浓度15％（V／V），提取时间30min，提取温度35℃，超声波功率500W；此条件下提取桦树鞣质，收率达到5．74％，纯度为45．68％。The technique for the extraction of White birch bark tannin by ultrasonic was optimized using uniform design. And the optimum conditions of ultrasound-assisted extraction of Birch tannin were obtained as follows： Ethanol concentration of 15% （V / V）, extraction time 30min, and ultrasonic power 500 W. The yield of extraction birch tannins was 5.74% under this condition, and the purity was 45.68%.
