Ultrasonic assisted extraction of polyphenol from eleocharis tuberose peel was optimized by an orthogonal test. The results showed that the extraction rate of polyphenol is mostly influenced by time , followedby ethanol concentration, ratio of solid-liquid and temperature. The optimum process parameters were temperature 50℃, ethanol concentration 60%, ratio of solid-liquid 1∶16 (g/mL) and time 20 min. Under these conditions, the extraction yied was 3.00%.
