摘　　要：采用超临界CO2萃取技术提取川佛手中的总黄酮,通过单因素分析和正交试验,确定了川佛手中总黄酮的最佳提取工艺参数,即萃取压力为30 MPa,萃取温度为50℃,料液比为100∶120 g/mL和萃取时间为2.0 h,在此条件下总黄酮的萃取率达到3.79﹪.The total flavonoids was extracted from Chuan Bergamot by supercritical CO2 extraction. The optimal parameters were determined as follows：extraction pressure was 30 MPa;extraction temperature was 50 ℃;solid-liquid ratio was 100：120（ g/mL）and extraction time was 2. 0 h by single factor tests and orthogonal experiments. Under these conditions,the extraction yield of total flavonoids is 3. 79%.
